3 Overview Hands-on Training Module Objective Companies today conduct much of their business online. Whether for corporate communications, websites for product and service information or sales, or server-hosted apps that run across a variety of end-user devices, companies rely on secure, reliable network connectivity in order to function and prosper. As the volume of a company s network traffic increases, so does the need for robust, resilient, and reliable network infrastructure that can not only sustain the network traffic, but optimize it. Gaining optimum efficiency in network connections, whether between private company assets across semi-private telecommunications channels, or between companies and their customers across the public internet, is a key asset to any company s operations. Citrix NetScaler, leveraging Load Balancing, optimizes and enhances the reliability of network infrastructures to allow better, more secure network communications, regardless of device or protocol. In this hands-on lab, we will configure Citrix NetScaler s Load Balancing, Custom Monitors, and Responder features in tandem with Microsoft Exchange The exercises shown in this hands-on lab guide will allow administrators to work with the features focused on the replacement of Microsoft Threat Management Gateway with Citrix NetScaler. Challenges: Providing increased reliability of services, even in the face of individual server downtime Ensuring that communications facilitate business operations while not introducing potential security threats Optimizing the user experience when access services Provide a replacement for the existing web proxy (Microsoft Threat Management Gateway) Prerequisites Basic understanding of deployment scenarios of the Citrix NetScaler. Basic understanding of deployment scenarios of Microsoft Exchange Basic understanding of the Microsoft Exchange 2013 management console. Audience Citrix Partners Customers Sales Engineers 2

7 Scenario AnyCo, Inc. has requested that a Sales Engineer demonstrate to their executive IT staff a solution that can improve the reliability and operational continuity of their infrastructure while also enhancing their network security as they increase the amount of traffic that must flow between their internal network and the public internet. Likewise, they also want to ensure that these additional security and functionality enhancements do not impede their available throughput or negatively impact their employees day-to-day productivity. Citrix NetScaler, through its Load Balancing feature, can provide all of these abilities and more. In order to improve availability system-wide and provide service redundancy, your goal is to assist AnyCo, Inc. with their challenges outlined below, and ensure that these solutions fit their business needs. Challenges: The customer wants to make sure that their services continue despite server maintenance or unexpected downtime in any one site s sent outside the company should reveal as little network information as possible about the sender s environment Fluctuating volumes of and other network traffic should not affect users experience working within the company s network Users experience should be considered when accessing web services Replacement of the current web services proxy, current web services proxy is end of support December

14 11. Enter the following Subnet IP Address and click Done. Subnet IP Address: A subnet IP address is used by the NetScaler to communicate with the backend servers. NetScaler uses this subnet IP address as a source IP address to proxy the client connections as well as to send monitor probes to check the health of the backend servers. 12. Proceed to click the Host Name, DNS IP Address, and Time Zone boxes on the initial NetScaler configuration wizard to enter the Host Name, DNS IP Address, and Time Zone for the Site1-NS1 NetScaler ADC. 13

15 13. Enter the following Host Name, DNS IP Address, and Time Zone and click Done. Host Name: NS1 DNS IP Address: Time Zone: GMT-4:00-EDT-America/New_York 14. Proceed to click the Licenses box on the initial NetScaler configuration wizard to confirm the license for the Site1-NS1 NetScaler ADC. 14

Surge Protection: This feature ensures that connections to the server occur at a rate which the server can handle. The response rate depends on how surge protection is configured. The NetScaler appliance also tracks the number of connections to the server, and uses that information to adjust the rate at which it opens new server connections. Web Logging: This feature send logs of HTTP and HTTPS requests to a client system for storage and retrieval. This feature has two components: The Web log server, which runs on the NetScaler. The NetScaler Web Logging (NSWL) client, which runs on the client system. When you run the NetScaler Web Logging (NSWL) client: 1. It connects to the NetScaler. 2. The NetScaler buffers the HTTP and HTTPS request log entries before sending them to the client. 3. The client can filter the entries before storing them. 18

37 23. Click the small blue disk to save the NetScaler configuration. Click Yes to confirm. Exercise Summary In this exercise, you configured Service Monitors, which allow the Citrix NetScaler to continually communicate with and verify the availability of the associated servers. By monitoring the status and availability of the servers, Citrix NetScaler can ensure that it is always passing network traffic to backend servers and resources that are online and available to serve the content that incoming client connections are requesting. Likewise, monitoring the backend servers allows the Citrix NetScaler to redirect traffic when necessary in order to ensure continuity of service availability. 36

38 Exercise 3 Configuring Service Groups for Exchange 2013 Overview In this exercise, service groups are used to bind together both the previously created custom monitors and the two existing Microsoft Exchange backend servers (Site1-Exchange and Site2- Exchange). Each service group will contain the same backend servers, but use unique monitors for each virtual directory used with Microsoft Exchange. Administrators are typically accustomed to using traditional services with Citrix NetScaler for this type of implementation, however with traditional services the same backend server cannot be used repeatedly. This exercise covers 4 of the 7 Service Groups that can be created when Load balancing Microsoft Exchange with Citrix NetScaler. Each of the service groups will use the same backend servers but are unique in their respective monitor. The monitors used to this exercise will be the following. OWA-Mon (Outlook Web Access) ECP-Mon (Exchange Control Panel) Autodiscover-Mon (Autodiscover Monitor) ActiveSync-Mon (ActiveSync Monitor) Step by step guidance Estimated time to complete this lab: 30 minutes. 37

136 Exercise 7 Configuring Single Sign On for Exchange 2013 Overview The goal of this exercise is to solve two major challenges. The first challenge is to improve user experience by leveraging the NetScaler s ability to provide single sign on services. The second is to provide added security. Upon completing these exercises the administrator will have created a custom form allowing users to directly authenticate on the Citrix NetScaler. The NetScaler will then forward these credentials to any available Exchange Server and securely authenticate the user allowing for one simple sign on. This will then enable administrators to place the Citrix NetScaler in the DMZ resulting in no publicly accessible Exchange Servers. Step by step guidance Estimated time to complete this lab: 30 minutes. Step Action 1. Using Internet Explorer, proceed to type the below URL and credentials to logon to the Site1-NS1 NetScaler.
