22Introducing the VPN Gateway

•Private network authentication. Existing authentication servers within the customer’s private network can be used.

•Access control. Unique access rules can be specified for each user group in the various VPNs.

•Private network name resolution. If desired, private network DNS servers can be mapped to the VPN.

•Split administration. VPN Portal management is enabled for each VPN customer through a web interface, without exposing global administration access.

•High availability. The Secure Service Partitioning solution is compatible with the NVG cluster’s high availability solutions.

Branch Office Tunnels

The NVG software provides the ability to configure IPsec-based branch office tunnels. Several peer-to-peer branch office tunnels can be configured for each virtual private network (VPN).

The following number of branch office tunnels can be configured per hardware model:

•NVG 3070: 2500

•NVG 3050: 1000

•Nortel 2424-SSL Application Switch: 500

For example, a cluster of two NVG 3070s support 5000 branch office tunnels.

Portal Guard

Feature used to "convert" an existing HTTP site to generate HTTPS links, secure cookies and so on. The VPN Gateway will not only handle the SSL processing but also see to it that all existing web links are rewritten to HTTPS. This eliminates the need to rewrite each link manually. Requires a license.

SSL Acceleration

The NVG software also includes features for SSL acceleration. Note that these features in some cases require interoperation with a Nortel Application Switch.

•Supports accelerated SSL processing by offloading SSL encryption and decryption from backend servers.

•Supports load balancing of encrypted and unencrypted traffic for up to 256 backend servers, with health checking and persistent client connections.
