(resolved) Multiple srcds Server at once?

[Funky_fire]

Hello I am trying to run a Counter Strike Source Server and a Garrys Mod Server at once. They both run correctly if only one if running. I have tried to follow This tutorial I do this: "Go to your Network properties screen and click on TCP/IP. Now click on properties and advanced. Under the box Ip Addresses you can simply add or remove several IP addresses." ,but once I do that I lose internet connection. Do I just put a random ip or what do I put when it says add or remove several ip address?
Help would be greatly appreciated. Thanks in advance!

BASIC INFO
Server OS: Windows XP Professional
Game(s): Garrys Mod, Counter Strike Source
Admin Mods: Mani Admin for CSS, NONE for Garrys Mod
(If you need more info just tell me and list it )

Add -port 27025 to the GarrysMod server. (Add it in the startup line)

Thanks for the quick response, however I added that line to the batch file that starts the garrys mod and I does not work. When I look for it in the master server list only my css server comes up.
GarrysMod Batch file below:
@echo off
cls
echo Protecting srcds from crashes...
echo If you want to close srcds and this script, close the srcds window and type Y depending on your language followed by Enter.
title srcds.com Watchdog
:srcds
echo (%time%) srcds started.
start /wait srcds.exe -console -game garrysmod -port 27025 +map gm_construct +maxplayers 16
echo (%time%) WARNING: srcds closed or crashed, restarting.
goto srcds

Try to do it with your Counter-Strike: Source server then.
