Why is my INTERNET server LAN!!?!?!!?!?

[vancar6]

I am running on a IBM server, it worked 3 months ago until i updated it.
I have all of the right ports forwarded.
I have reinstalled it all too.
It only shows up the LAN IP.
This is annoying, please help me.
CPU:
Pentium 4 1.8 GHZ
1GB Ram
Windows XP Home 32 Bit.
Garry's Mod is what im hosting.
20 Slots, on the right ports.
-console -game garrysmod +map gm_construct +maxplayers 16
Is my command line.

Try and add +sv_lan 0 else we need more info, like how your port forward looks and such.

It will always show up on your local LAN.
Other will be able to connect via your external IP if you have the ports forwarded correctly.

Also, don't expect much power out of that old P4.
