GMOD Server no one can connect.

[iiHeroz]

I have made a DarkRP Garry's Mod Server using srcds but the problem is that I can join the server using my internal IP but my friends cant join with the external. Link to portforward: http://puu.sh/eFRGL/158b2fe089.png Link to canyouseeme.org: http://puu.sh/eFRQN/4233ffa398.png No matter what port I put in from my portforward it was say it cant see it. I'm not sure what to do, it seem's as if my portforward is right as I used my ipv4 but when I give people my external ip it wont connect them. Would like some information or a fix for this, thanks@

.bat file:
@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 +gamemode darkrp +map rp_subterranean +maxplayers 16
echo (%time%) WARNING: srcds closed or crashed, restarting.
goto srcds

try to run the original srcds.exe and adding the command sv_lan "0" to server.cfg
