Need to set up a site-to-site vpn b/w home and branch office. The branch office is connecting back to its ISP via 2 E1 circuits. We are load balancing between the 2 E1's via static routes. In the past I have terminated VPN tunnels on the WAN facing IP address. However, in this case I have two different IP addresses for each E1. Are there any caveats in moving the VPN endpoint to the LAN facing interface on the router? Is there a better design approach that is more commonly used with this type of topology? thanks in advance.
I have this problem too.
