VPN + NAT + ISDN = Stumped: msg#00137network.nsp.cisco
Hello, I checked the archives, unless I missed something, the list discussion fizzled a similar question by Ray Davis at Carpnet. The SA session establishes, and that's about it. Private Hosts on either end are unable to see each other. I must be missing something? The config that I used on the ISDN side works on a router that uses a DSL circuit. The only differance I can see is Dialer 0 on the ISDN router vs. fa0 on the DSL router.
