So I am having issues with port forwarding to a private IP on the inside…below is the config for the two fast ethernet interfaces. I have removed all the ACL’s in hopes that it was that, but unfortunately it did not prove true.

When I do a show ip nat translation it looks like its listening and I should be able to connect, but I can’t.

NRouter#show ip nat translations
tcp 209.33.98.76:2368 172.16.61.140:2368 — —
tcp 209.33.98.76:6320 172.16.61.140:6320 — —
tcp 209.33.98.76:61002 172.16.61.140:61002 — —
udp 209.33.98.76:61031 172.16.61.140:61031 — —

I am testing this theory by trying to telnet from the outside to the machine. I have telneted to the machine within the private network and I get a response so I definitely know the machine is listening. Hopefully you’ll see something that I am not.
