I've looked at it before but never with a task in mind, so I looked again now. Using the example where I guess Host X is ISP#1, Host A is Buddy's router, Host B is ISP#2, Host C is my router and Host D is the duplicate router: Will the Host D "look like" the real router? i.e. if from the cloud somewhere I do "ssh HostA" will I be connecting to A or D? I guess the routed subnet should happily get to D so my real concern is to transparently make D look entirely like A for traffic to and from. Thanks again, *** NOTE *** Please DO NOT CC me.
