BTDT - You need to not only forward the ports but pass them explicitly 
IN in the ipf.rules file.

Also check to see that you can get to it from inside the network.  As 
well as any subnet restrictions the telnet daemon could possibly have - 
localhost only, network A not network B, etc.

*blink*

Also WTF are you using telnet for!!!!!!!!!!   Use SSH if at all 
possible.
To do anything else is to invite an intrusion.
