It might well mean that the question being asked is how to allow in-bound connections to telnetd.
(Some router / dsl modems misuse "forward" in this sense.)
If such is the case, then the O.P. wants to know how to open port 23 for in-bound connections in iptables (firewall).
The best place to do that is in the iptables save file, so that the rule is set on every reboot.
