6 2 Overview This section provides an introduction to application offloading and HTTP(S) bookmarks. This section contains the following subsections: What are HTTP(S) Bookmarks and Application Offloading? on page 4 Benefits of HTTP(S) Bookmarks on page 5 Benefits of Application Offloading on page 5 How Does Application Offloading Work? on page 5 Supported Platforms on page 6 Software Prerequisites on page 8 What are HTTP(S) Bookmarks and Application Offloading? Dell SonicWALL Secure Mobile Access uses HTTP(S) bookmarks and application offloading on Dell SonicWALL SMA/SRA appliances to provide access to Web-based applications running on servers within the intranet. This includes SharePoint 2007, SharePoint 2010, and the enhanced versions of commonly used Web mail interfaces, such as Microsoft OWA Premium and Lotus Domino Web Access. SharePoint 2010 is supported with application offloading. Both application offloading and HTTP(S) bookmarks use an HTTP(S) reverse proxy. A reverse proxy is a proxy server that is deployed between a remote user outside an intranet and a target Web server within the intranet. The reverse proxy intercepts and forwards packets that originate from outside the intranet. An HTTP(S) reverse proxy specifically intercepts HTTP(S) requests and responses. Application Offloading provides secure access to both internal and publicly hosted Web applications. An application offloading host is created as a special-purpose portal with an associated virtual host acting as a proxy for the backend Web application. Unlike HTTP(S) bookmarks, access to offloaded applications is not limited to remote users. The administrator can enforce strong authentication and access policies for specific users or groups. For instance, in an organization certain guest users may need Two-factor or Client Certificate authentication to access Outlook Web Access (OWA), but are not allowed to access OWA public folders. If authentication is enabled, multiple layers of Dell SonicWALL advanced authentication features such as One Time Password, Two-factor Authentication, Client Certificate Authentication and Single Sign-On can be applied on top of each other for the offloaded host. The offloaded application portal must be configured as a virtual host with a suitable Dell SonicWALL SMA domain. It is possible to disable authentication and access policy enforcement for such an offloaded host. Web transactions can be centrally monitored by viewing the logs. In addition, Web Application Firewall can protect offloaded application hosts from any unexpected intrusion, such as Cross-site scripting or SQL Injection. Access to offloaded Web applications happens seamlessly as URLs in the proxied page are not rewritten in the manner used by HTTP or HTTPS bookmarks. 4

7 Benefits of HTTP(S) Bookmarks By using HTTP(S) bookmarks, users can access the full-featured versions of SharePoint 2007, SharePoint 2010, Microsoft OWA with Autodiscover, Microsoft OWA Premium, and Domino Web Access Web mail interfaces. These interfaces are easier to use and provide more enhanced features than their basic counterparts. For a full description of the application features supported using application offloading and HTTP(S) bookmarks, refer to the following sections: SharePoint server 2007 on page 28 SharePoint server 2010 on page 29 SharePoint server 2013 on page 29 Lotus Domino Web Access support on page 31 Benefits of Application Offloading An offloaded Web application has the following advantages over the Web application as an HTTP(S) bookmark in the Dell SonicWALL SMA/SRA appliance: No URL rewriting is necessary, thereby improving throughput significantly. The functionality of the original Web application is retained almost completely, while an HTTP(S) bookmark is a best-effort solution. Application offloading extends the Dell SonicWALL SMA/SRA appliance security features to publicly hosted Web sites. Application offloading can be used in any of the following scenarios: To function as an SSL offloader to offload encryption operations for Web servers and add HTTPS support to the offloaded Web application, using the integrated SSL accelerator hardware of the Dell SonicWALL SMA/SRA appliances. In conjunction with the Web Application Firewall subscription service to provide the offloaded Web application continuous protection from malicious Web attacks. To add strong or stacked authentication to the offloaded Web application, including Two-factor authentication, One Time Passwords and Client Certificate authentication. To control granular access to the offloaded Web application using global, group or user based access policies. To control access to internal Web sites using host, URL, or port based access policies As an SSL accelerator to enhance throughput over the Internet using caching, compression, connection persistence and multiplexing To support Web applications not currently supported by HTTP/HTTPS bookmarks. Application Offloading does not require URL rewriting, thereby delivering complete application functionality without compromising throughput. How Does Application Offloading Work? For example, Application Offloading portals can be used for Web applications and sites that already exist and could be accessed directly, such as an internal Web application, a resource on the internal network, or a public site. When using Application Offloading portals, remote access to these sites or applications is controlled by the Dell SonicWALL SMA/SRA appliance and mapped to Application Offloading portals that are protected by other functions of the Dell SonicWALL SMA/SRA appliance, such as SSL encryption and Web Application Firewall. 5

If one specific network interface is selected, a new IP address is assigned to the portal. 4 The Portal Certificate drop-down lists all certificates that have been imported. 5 The Load Balancing Group field replaces the Application Server Address field to show the existing Load Balancing Group to which you can assign to this portal. If no Load Balancing Group exists, you can create a new one by clicking click here to create. All these settings are verified instantly from the Appliance when the mouse leaves the input field (green check). If the input fails, the reason it failed is shown. Only when all fields are satisfied, can you click Next to go to the next tab. URL-based Aliasing Server Settings Select URL Based Aliasing on the initial page when you want the ability to access several Web sites using one portal and domain name. When this option is enabled, the screen options change. You will need to select the 12

15 URL Based Aliasing Group from the drop down list. When URL Based Aliasing is selected on the initial page, the Server step appears as follows. 1 In the Portal Name field, enter a unique name to identify different portals. 2 In the Portal Domain Name field, enter the domain name used to access the offloading portal. 3 In the Portal Interface field, enter the network interface to which the portal is bound. If one specific network interface is selected, a new IP address is assigned to the portal. 4 The Portal IP Address field is not required if All Interfaces is selected in the Portal Interface field, but you need to enter the Portal IP Address of specific X0, X1, X2, and X3 interfaces. 5 The Portal Certificate drop-down lists all certificates that have been imported. 6 Any existing URL Based Aliasing Group(s) are listed in the drop-down and available to assign to this portal. If no URL Based Aliasing Group exists, you can create a new one by clicking the click here to create hyperlink. All these settings are verified instantly from the Appliance when the mouse leaves the input field (green check). If the input fails, the reason it failed is shown. Only when all fields are satisfied, can you click Next to go to the next tab. 13

16 Configuring the Security Settings The third step is for the Security settings, including Enable Web Application Firewall and Disable Authentication Controls. However, both options require a Web Application FIrewall license. 14

17 Configuring the Miscellaneous Settings The fourth and last step includes the general portal settings. 1 Enter the title for the Web browser window in the Portal Site Title field. 2 To display a banner message to users before they login to the portal, enter the banner title text in the Portal Banner Title field. 3 Enter an HTML compliant message, or edit the default message in the Login Message field. This message is shown to users on the custom login page. 15

18 Editing the General Portal Settings 1 Navigate to Portals > Portals and click the Configure icon for the portal you would like to edit. The General tab of the Portal Settings screen opens. This allows you to access the Portal directly. 2 You can edit the Portal Name, Portal Site Title, the Portal Banner Title, and the Login Message as needed. 3 To enable visibility of your custom logo, message, and title information on the login page, select the Display custom login page check box. NOTE: Custom logos can only be added to existing portals. To add a custom logo to a new portal, first complete general portal configuration, then add a logo. 4 Select the Display login message on custom login page check box to display the login message (from the Login Message field) when users log into the custom login page. 5 Select the Hide Domain list on portal login page check box to replace the Domain list box displayed on the login page to a text box for you to type in the correct domain name. 6 Select Enable HttpOnly for SMA cookies to secure SMA cookies using the HTTPOnly flag. Some client-side technologies such as Java applets do not have access to cookies marked HTTPOnly. This can break access to the web application when using an HTTP/HTTPS Bookmark or the App Offloading Portal. Disable this option to restore compatibility for these web applications. 7 Select the Enable HTTP meta tags for cache control check box to apply HTTP meta tag cache control directives to the portal. Cache control directives include: <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="cache-control" content="must-revalidate"> 16

19 These directives help prevent client browsers from caching the Dell SonicWALL SMA/SRA appliance portal pages and other Web content. NOTE: Enabling HTTP meta tags is strongly recommended for security reasons and to prevent out-of-date Web pages and data being stored in a user Web browser cache. 8 Select the Enforce login uniqueness check box to restrict each account to a single session at a time. When login uniqueness is not enforced, each account can have multiple, simultaneous sessions. 9 Select the Enforcement method. Options include Automatically logout existing session and Confirm logout of existing session. 10 Select the Enforce client source uniqueness check box to prevent multiple connections by a user with the same client source address when connecting with a Dell SonicWALL client (NetExtender, Mobile Connect, Virtual Assist etc.). This prevents a user from consuming multiple licenses when a user reconnects after an unexpected network interruption. For example, a user on an unreliable network is disconnected due to a network issue. If login uniqueness is NOT enabled, the user session on the appliance stays active for this type of disconnect until the timeout value is reached. The user reconnects and consumes a second license with the potential of consuming more licenses before the original connection timeout disconnects them. 11 Specify the link(s) for the Small / Medium / Wide / Large Logo to be used with Live Tile. 12 Specify the Background Color for Live Tile. If no value is specified, the default color is #0085C3. 13 Specify the Site Name to be displayed for Live Tile. If no value is specified, the default is the Portal Name. 14 Click Accept to preserve your settings. Configuring the Offloading Settings 1 Navigate to Portals > Portals and click the Configure icon for the portal you would like to edit. The General tab of the Portal Settings screen opens. 17

20 2 Click the Offloading tab. The Application Offloader Settings screen appears. 3 On the Offloading tab, select the Enable Load Balancing check box for load balancing among offloaded application servers. 4 Select the Enable URL Based Aliasing check box. As a result, some fields become hidden and the Enable URL Rewriting for self-referenced URLs check box is automatically selected. 5 Select the group you wish to add a portal for from the URL Based Aliasing Group drop down list. 6 If not using a URL Based Aliasing Group, select one of the following from the Scheme drop-down list: Web (HTTP) access the Web application using HTTP (default scheme) Secure Web (HTTPS) access the Web application using HTTPS Auto (HTTP/HTTPS) allows the user to determine the actual scheme used to talk to the backend server when accessing an offloading portal. Access is still under the control of the access policy. When using the Auto scheme, users can type or in browser s address bar to test this feature. Even scheme set to Auto, it s still under the control of the access policy. CAUTION: It is the Administrator s responsibility to configure the correct scheme used to talk to the backend server. Auto (HTTP/HTTPS) Scheme can operate only if HTTP access is enabled for the Virtual Host (under the Virtual Host tab) and authentication is disabled (under the Offloading tab), which may be insecure. Therefore, you will be prompted to click OK to enable HTTP for Virtual Host and enable Anonymous access. 7 Enter the host name or private IP address of the backend host into the Application Server Host field. 8 Optionally enter the IPv6 address of the backend host into the Application Server IPv6 Address field. 9 In the Port Number (optional) field, optionally enter a custom port number to use for accessing the application. 18

21 10 In the Homepage URI (optional) field, optionally enter a URI to a specific resource on the Web server to which the user will be forwarded the first time the user tries to access the Application Offloading Portal. This is a string in the form of: /exch/test.cgi?key1=value1&key2=value2 When this field is configured, it redirects the user to the Web site s home page the first time the user accesses the portal. This happens only when the user is accessing the site with no URL path (that is, when accessing the root folder, for example: This is not an alias for the root folder. The user can edit the URL to go back to the root folder. The key=value pairs allow you to specify URL query parameters in the URL. You can use these for any Web site that does not have a default redirect from the root folder to the home page URL. Outlook Web Access is one example, but note that most public sites do have a default redirect. 11 Select a Proxy Host from the drop-down menu. Options include Inherited from client request, Virtual Hostname, and Application Server Host (backend). The Inherited from client request option is the default value. Security Settings 1 Under Security Settings, select the Enable Web Application Firewall button to enable the feature. 2 Select Disable Access Policies to prevent existing Access Policies from taking precedence. 3 Select the Disable Authentication Controls, Access Policies, and CSRF Protection (if enabled) check box if you need no authentication, access policies, or CSRF protection enforced. This is useful for publicly hosted Web sites. 4 To configure ActiveSync authentication, clear the Disable Authentication Controls check box to display the authentication fields. Select the Enable ActiveSync authentication check box and then type the default domain name. The default domain name will not be used when the domain name is set in the client s setting. 5 Select the Automatically Login check box to configure Single Sign-On settings. 6 For Automatically log in using SSO, select one of the following radio buttons: Use SSL-VPN account credentials allow login to the offloaded application using the credentials configured on the Dell SonicWALL SMA/SRA appliance Use custom credentials displays Username, Password, and Domain fields where you can enter the custom credentials for the application or use dynamic variables. For the Password field, enter the custom password to be passed, or leave the field blank to pass the current user s password to the offloaded application portal. For the other fields, dynamic variables can be used, such as those shown below: Table 1. Supported dynamic variables Text Usage Variable Example Usage Login Name %USERNAME% US\%USERNAME% Domain Name %USERDOMAIN% %USERDOMAIN\%USERNAME% Group Name %USERGROUP% %USERGROUP%\%USERNAME% 7 If you selected Automatically Log in, select the Forms-based Authentication check box to configure Single Sign-On for forms-based authentication. 19

22 Configure the User Form Field to be the same as the name and id attribute of the HTML element representing User Name in the Login form, for example: <input type=text name= userid > Configure the Password Form Field to be the same as the name or id attribute of the HTML element representing Password in the Login form, for example: <input type=password name= PASSWORD id= PASSWORD maxlength=128> 8 Select the Enable Clients Authentication check box to allow the portal to be accessed by clients, such as ActiveSync or Outlook. Specify a Default Domain Name from the drop down list. The Domain Name is used as the default for Dell SonicWALL SMA authentication if the domain name is not specified in the client. NOTE: This option is not necessary for OWA. Configuring Virtual Host Settings Creating a virtual host allows users to access the application using a different host name than your default URL. For example, sales members can access instead of the default domain, that you use for administration. The portal URL (for example, will still exist even if you define a virtual host name. Virtual host names enable administrators to give separate and distinct login URLs to different groups of users. URL rewriting should be enabled in this case. To avoid the need for URL rewriting, use the same FQDN for the Virtual Host Name and the application server site. To configure the settings on the Virtual Host tab for an offloaded application portal: 1 Enter a host name in the Virtual Host Domain Name field, for example, sales.company.com. Only alphanumeric characters, hyphen (-) and underscore (_) are accepted in the Virtual Host Domain Name field. 2 Optionally enter a descriptive alias in the Virtual Host Alias field. 3 If you are using IP based virtual hosting, select a specific Virtual Host Interface for this portal. If using name based virtual hosts where more than one hostname resides behind a single IP address choose All Interfaces. When selecting All Interfaces, you can import a wildcard certificate for all virtual hosts on the Dell SonicWALL SMA/SRA appliance. See Step 6. 4 If you selected a specific interface for this portal in the previous step, enter the desired Virtual Host IP Address in the field provided. This is the IP address users will access in order to access the portal. NOTE: For external access, be sure to add an entry in your external DNS server to resolve the virtual hostname and domain name to the external IP address of your Dell SonicWALL SMA/SRA appliance. 5 If you selected a specific interface for this portal, you can specify an IPv6 address in the Virtual Host IPv6 Address field. You can use this address to access the virtual host. Enter the IPv6 address using decimal or hexadecimal numbers in the form: 2001::A987:2:3: If you plan to use a unique security certificate for this sub-domain, select the corresponding port interface address from the Virtual Host Certificate list. If you need to associate a certificate to this host, first import the relevant SSL certificate into the Dell SonicWALL SMA/SRA appliance: For name-based virtual hosting, you can import a wildcard certificate to use for all virtual hosts on the Dell SonicWALL SMA/SRA. 20

23 For IP-based virtual hosting, import a regular SSL certificate. This type of certificate includes the hostname of the server. NOTE: Unless you have a certificate for each virtual host domain name, or if you have purchased a *.domain SSL certificate, your users may see a Certificate host name mismatch warning when they log into the portal. The certificate hostname mismatch only affects the login page; the Dell SonicWALL SMA/SRA appliance client applications will not be affected by a hostname mismatch. NOTE: Some ActiveSync clients do not work well with servers that have invalid SSL certificates. 7 Select the Enable Virtual Host Domain SSO check box to allow users logged into this portal to automatically log into other portals or Web sites that share the same Virtual Host Domain. Configuring an HTTP/HTTPS Application Offloading Portal To offload a Web application and create a portal for it: 1 Navigate to Portals > Portals and click the Virtual Host tab. The Virtual Host Settings screen opens. This allows you to access the Portal directly. 2 Enter a descriptive name in the Virtual Host Domain Name field. 3 On the Virtual Host tab, set a host name for the application in the Virtual Host Domain Name field, and optionally enter a descriptive alias in the Virtual Host Alias field. If you need to associate a certificate to this host, you should additionally set a virtual interface and import the relevant SSL certificate. You could avoid creating a virtual interface by importing a wildcard certificate for all virtual hosts on the Dell SonicWALL SMA/SRA appliance. 21

24 4 If authentication is disabled for this portal, you have the option to Enable HTTP access for this Application Offloaded Portal. This feature is useful for setting up offloading in trial deployments. 5 Click Accept. You are returned to the Portals > Portals page where you will see the Web application listed as an Offloaded Web Application under Description. 6 If you have not disabled authentication, navigate to the Portals > Domains page and create a domain for this portal. 7 Update your DNS server for this virtual host domain name and alias (if any). 22

25 Using Offloaded Applications An offloaded application has its own portal page on the Dell SonicWALL SMA/SRA appliance. The portal can be accessed directly by entering the URL in a Web browser. You can also create an External Web site Bookmark on the Dell SonicWALL SMA Virtual Office portal that takes you to the offloaded application portal. To use an offloaded application: 1 For direct access, point your Web browser to the URL of the offloaded application portal. 2 For access via an External Web site Bookmark, log into the Dell SonicWALL Virtual Office and then click on the bookmark. A new window is launched in your default browser that connects to the offloaded application portal specified in the bookmark. 3 On the portal page, enter your login credentials to access the application if authentication is required. 23

26 Configuring and Using HTTP(S) User Bookmarks 4 Dell SonicWALL uses HTTP(S) bookmarks on Dell SonicWALL SMA/SRA appliances to provide access to Web-based applications running on SharePoint 2007 servers within the intranet. This section contains the following subsections: Configuring an HTTP(S) user bookmark on page 24 Using HTTP and HTTPS bookmarks on page 26 Using HTTP(S) bookmarks with SharePoint and Lotus Domino on page 26 Configuring an HTTP(S) user bookmark To create HTTP or HTTPS user bookmarks: 1 Log into your Dell SonicWALL SMA/SRA appliance. 2 From the Users tab, select either Local Users or Local Groups. 3 Click the Configure icon next to the user or group for which you want to create the bookmark. 4 Select the Bookmarks tab. 24
