I just installed a new Nortel VPN Route 1750, everything is working great except one application on a UNIX server. The server is listening on port 513, I've pulled packets and see traffic back and forth but never get the login and get a socket failure, it looks as the the client is trying to respond on port 2003 and not 513. The firewall is wide open, I can telnet to the UNIX box on 513 and PuTy to it from this client. The tunnel packet sniff never shows rlogin requests coming into the client. I ve looked online on Nortel's website, Googled it and even have a ticket open with Nortel..no luck yet.
