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

Subject: Re: [CentOS] TCP/IP Port Relay
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.
