IOS VPN Server and Client issues on 1720 with VPN module.
I am trying to set up our 1720 to act as a vpn server for our developers so they can access the DMZ I created with a second ethernet WIC in the router. I have udp 500 and 4500 open to the router and using local authentication. The client prompts for username and password and makes it all the way to "Securing communications channel..." and just hangs there forever. Is there something basic that I'm missing here? I'm using 12.2.15 ios version which supports transparent NAT capabilities, so I don't think it's a NAT/PAT issue, but I am new to this. If someone could give me some pointers that would be great, I seem to have exhausted the config examples on the site here.

Difficult to say what's going on. Can you post the router config, making sure to xxxxx out your outside IP address(es) and your passwords? Can you also run "debug cry isa" and "debug cry sa" and try a connection, then post that output also (again, xxxx out the external IP address in the debug)
