Cisco IOS help

[Fuzznuts]

i am trying to forward a range of ports into a server from a 2503 router for single ports it is no problem and wokrs fine with

ip nat inside source static tcp 192.168.0.2 25 interface serial 1 25

but how would i do this for a range of ports for a game server that needs 100 or os ports forwarded of course i could add them one by on but there has to be and easier way.

any help mucho appreciated.

After doing a little research at the Cisco TAC it doesn't appear that there is a way to forward a range of ports. But, I have all the documentation on Cisco's ip nat commands should you want them. Just send me a PM with your e-mail address and it will be yours.
