As a lab exercise, conducted because an upstream provider would only provide one router IP, I set up two Soekris 4801s with their external interfaces just "up" -ed and used the exclusive global IP for carp. It worked like a charm. The internal interfaces could have had whatever addresses I wanted but, just for fun, I made them work the same way as the externals. I could have left selective accesses to the 4801s as an exercise "for the reader" but just think of the 172.20.30/24 I assigned for the link between the two.... *** NOTE *** Please DO NOT CC me.
