We have an AT&T managed VPN between 2 office locations. Location A uses 192.168.1.0. Location B uses 192.168.2.0. All of the sudden, traffic cannot travel from A to B, but CAN travel from B to A. We can resolve names from A to B, but any attempts to ping or tracert items in B stop at the B gateway (192.168.2.1). Any ideas?
