I have a route-based vpn from my site (Netscreen204) to a customer site (Fortinet) . They want a second, backup tunnel in case of failure, and will be using the Fortune there too.
The only thing I don't quite get is how best to set up vpn monitor. Can I set up a loopback interface that can ping some destination in their domain? Does that loopback have to be from the IP range that I specified in the proxy-id locally?
