Chapter 5

Configure a Secure Connection to a VPN

Appliance

In this scenario, a VPN appliance (such as a firewall) establishes the IPsec

association with the 1756-EN2TSC module. Client workstations or other

modules then establish IPsec associations with the VPN appliance. The VPN

appliance then routes packets between the IPsec associations.

The IPsec association between the VPN appliance and module services multiple

remote (from the module’s point of view) devices and networks. You configure

the module to know which remote networks are routed via the VPN appliance.

This configuration lets you consolidate multiple VPN clients through a single

location (the VPN appliance). This limits the need for multiple secure tunnels to

each VPN client as you need only one secure tunnel between the 1756-EN2TSC

module and the VPN appliance.
