Port Overlap on a Wireless-G Broadband Router with SpeedBooster (WRT54GS)

I have just made a server not to long ago and I need help getting a port working as my router is not letting me forward a important port, in this case 27015 to 27015 UDP, so my server can be seen on the internet, or enterable, the server IP is

For starters, that’s your local IP, if you want other people to join you’ll need to give them your external.
