Routing Internet Traffic Through a Site-to-Site IPsec Tunnel

It is possible to use IPsec on a AZTCO-FW router to send Internet traffic from Site A such that it would appear to be coming from Site B. This may be needed if a vendor requires that connections originate from a specific address at Site B.

In this article we have two sites:

1. Site A is a branch office, LAN subnet 192.168.10.0/24
2. Site B is the main office through which all Internet traffic is routed, 192.168.20.0/24
