Yes, I was thinking along those lines, but I thought I'd ask. THANKS!

hmm, if I understood you correctly, then this should work just fine (on linux firewall):
/sbin/iptables -t nat -I PREROUTING -p tcp --dport 23 -j DNAT \ --to telnetserverip:port-number /sbin/iptables -I FORWARD -i external_interface -o internal_interface \ -p tcp -d telnetserverip --dport portnumberontelnetserver -j ACCEPT
after a reboot or firewall service restart it's gone again.

What is the best way to temporarily setup a port relay. I'm trying to diagnose a problem with Cisco's latest VPN client and need to determine if the problem is port number related.
e.g. VPN client---------23-(Linux box to relay port)-------xx-(Telnet server)
(Keep in mind this is temporary and for debugging purposes)
