I'm having some trouble setting up my 3030 concentrator to establish a tunnel with a PIX. The remote side, which I do not control, has an ACL that only allows telnet traffic on the VPN tunnel. When this ACL is active, the tunnel does not work. Phase 1 completes but it bombs out on phase 2. We tested by changing the ACL to allow any ip traffic and everything worked fine.
What do I need to do on the concentrator side to match this ACL? I have tried creating rules and adding them to a filter and applying it to the L2L for that tunnel, but that did not work.
Appreciate any help!
