Two-Armed Configuration 39

Interfaces

During the initial setup procedure (see “Configuration at Boot Up” (page 41)), you will be asked if you want to set up a one-armed configuration or a two-armed configuration.

One-Armed Configuration

In a one-armed configuration, only one interface is configured. It acts as both a public interface (facing the Internet) and a private interface (facing the intranet).

The interface (Interface 1) on the SSL VPN will handle public traffic, that is, client traffic from and to the Internet, as well as private traffic, that is, connecting the SSL VPN to internal resources and configuring the SSL VPN from a management station.

One-Armed Configuration without Application Switch

Two-Armed Configuration

In a two-armed configuration, two separate interfaces are configured on the VPN Gateway.

Interface 1 will handle private traffic (between the SSL VPN and the trusted intranet), that is, connecting the SSL VPN to internal resources and configuring the SSL VPN from a management station.

Interface 2 will handle public traffic, that is, client traffic from and to the Internet.

A two-armed configuration is considered more secure.
