General Information on Tunnels

A Tunnel is a mechanism provided by the Firewall that allows secure communications between secure networks over an nonsecure intervening network like the Internet. It constructs a virtual private network (VPN) between two different sites providing authentication and encryption. When you create a tunnel, a complete IP packet, including its header information, is encapsulated in a new IP packet only seen by the source and destination hosts. The original IP packet is protected during the transmission between hosts, according to user specified policy.

As a tunnel partner, you will receive tunnel context definitions that have been exported to you. When you receive these tunnel context definitions from a tunnel partner, you will place these files in a directory of your choice. Select Import, then enter the name of the directory where you have restored the files you have imported from your tunnel partner.
