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.
