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.

Sorry to jump in on someone else's thread, but... How do you do this if the interface you want to use is a virtual? Meaning it's eth0:1 for example? The -i parameter will not let you use that.
