4 what is Custom Connect? Many companies already use their own Virtual Private Network (VPN) solutions to allow remote workers to connect to corporate IT systems via non-secure access points. These may range from homeworkers using dial-up or broadband connections, through field-based employees logging on from customer sites, to executives using wireless hotspots in coffee shops, trains and airports. If you re moving towards location-independent working through mobilising new parts of your workforce, you may want to continue using your own VPN client software. Custom Connect is about enabling you to do that. We will work with you to help you achieve direct, secure connection from your users mobile devices to your corporate networks, via the Orange mobile network and using your own VPN solution. Under Custom Connect, your remote and mobile users will be able to access their corporate LAN from a handset, laptop or PDA, via the Orange GPRS, EDGE, 3G or 3G+ networks, using a business grade Access Point Name (APN) designed specifically for VPN usage. how it works Custom Connect uses a dedicated Access Point Name (APN), accessed via the Orange GPRS, EDGE, 3G or 3G+ networks. Instead of the standard orangeinternet APN, which is designed for standard browsing and contains additional optimisation and content filtering services, Custom Connect uses the dedicated internetvpn APN. internetvpn can be provisioned on the SIM of any data device that is required to be used with VPN client software. Orange Business Everywhere devices are automatically set up with this APN.

5 multiple APNs You can have more than one APN set up on a device, but swapping between APNs can be a little more complicated on some handsets. For data cards, the Business Everywhere Connection Manager software has orangeinternet scripted behind the internet button, and internetvpn scripted behind the office/vpn button as a default. From Business Everywhere version 8.0 onwards, the assignment of buttons and the scripting behind them is fully flexible and can be individually customised. This means you can configure the software to your company s specific requirements, ready to roll them out to your team. You can for example, let the software pick the best network for you, to meet your priorities for speed, cost and location. It s also where you can store all the security rules regarding remote access to business applications. Custom Connect enables you to: Provide simple, secure access for remote or mobile workers to office-based applications. Ensure that your existing IT security policies are enforced for mobile workers, especially when used with the Business Everywhere connection manager. Integrate mobile data handsets such as PDAs and SmartPhones with line-of-business applications (though a VPN client is required on the user device, which may slow down performance on smaller devices). Manage your own VPN and resilience strategy.

6 managing your VPN compatibility Custom Connect supports IPSec (ESP mode) and PPTP VPN protocols as standard. Other VPN protocols that are not sensitive to Network Address Translation (NAT) should also work. While we don t recommend any specific VPN client/servers, we have experience of a wide range of (typically IPSec) VPN implementations. Provided your vendor complies with the protocols above, your VPN overlay should operate successfully. Your Orange account manager will arrange for a discussion with our Technical Pre Sales team to iron out any specific issues or concerns about compatibility with your own IT systems. basic access Device Authentication Each user s device will be authenticated and authorised via the Orange SIM, to allow access to both the Orange network and the internetvpn APN. User Authentication This depends on the VPN client you use and your own security policy. Typically this will be a user name and password log-in prompt IP address allocation Device IP addresses are dynamically assigned by the GGSN, from the range specified by the customer. IP addressing at firewall The following NAT address ranges are used for internetvpn / 18 ( ) / 17 ( ) The NAT timer is 180s. IP addressing devices The following private address ranges are dynamically assigned by default: / 21 ( ) / 21 ( ) If you have issues with IP addressing or believe you are encountering private address conflicts, your account manager can arrange for a discussion with our Technical Pre Sales team to see if an alternative internetvpn assignment is required.

7 technology information IPSec VPNs IPSec VPNs are encrypted connections between private networks over a public network. They enable the internet to be used as the medium for transporting data between the Orange network and the customer LAN infrastructure. Powerful industrystandard IPSec encryption technology, and other security mechanisms, are used to ensure that only authorised users can access the network and that the data can t be intercepted. IPSec supports multiple protocols, has high reliability and extensive scalability. IPSec can be used to secure all communications between parties, by using authentication and encryption, without requiring any further modifications to applications or protocols. IPSec provides: Data Confidentiality The IPSec sender encrypts packets before transmitting them across the public internet. Data Integrity The IPSec receiver authenticates packets sent by the IPSec sender to ensure that the data has not been altered during transmission. Data Origin Authentication The IPSec receiver authenticates the source of the IPSec packets sent. This service is dependent on the data integrity service. Anti-replay The IPSec receiver can detect and reject replayed packets. what s an APN? An Access Point Name (APN) is the radio access equivalent of an ISP s dialup phone number. Customers can access their APN via a GPRS, EDGE, 3G or 3G+ enabled device. The mobile device will be configured with the appropriate settings to connect to any given APN. The SIM in the device must also be provisioned to access this APN. The APN provides routing information for the Serving GPRS Support Nodes (SGSN), and the Gateway GPRS Support Nodes (GGSN. The SGSN uses the APN name to firstly determine whether the mobile user is permitted to access the APN. The GGSN uses the APN configuration to assign an IP address and other parameters, as specified in the APN such as DNS,to the device.

8 connection security The Orange GSM infrastructure has been in use for a number of years, involving millions of users worldwide and has largely been proven as a secure environment. The Orange mobile network was designed with a high level of security built in. Orange was designed as a digital network from the outset, and as a consequence does not suffer from some of the security shortcomings in the original analogue networks. The GSM standards are well proven in terms of security, and this has been enhanced as the network has evolved to support GPRS, EDGE, 3G and 3G+ services. The primary security features of the Orange network include: Legitimate business systems can connect to the network All user data transmitted over the air interface is encrypted User identities are secured Encryption between the mobile device and the GPRS network changes each time the device connects to the network IP addresses are never transmitted in the clear over the air interface Connections between the enterprise and the Orange GPRS network using a VPN offer secure connections from end to end international roaming Custom Connect allows a user to connect to their APN when they re in Orange roaming partner countries, via GPRS, EDGE, 3G and 3G+ enabled networks. The mobile user seamlessly connects to the roaming partner s network, which connects them to their specific APN in exactly the same way as if they were in the UK. This service is completely transparent to the user. the internet Custom Connect is dependent on an existing customer internet connection. The customer s internet Service Provider (ISP) provides the connection from the customer site to the internet. The ISP will provide a network termination device, usually a router. Each ISP owns its infrastructure and interconnects with others to provide internet access to its clients. Within its network, an ISP can guarantee a level of service. The internet is fully resilient by design, and can be considered as reliable as a resilient leased line. However, it must be noted that no end-to-end Service Level Agreement (SLA) can be defined on any internet service.
