[resolved] Css not connecting

[rp42]

First, Hi i'm new here ^^
And now back to the topic...
I'm having some trouble with the server, I installed it correctly,and it worked. But when i installed the plugins (metamod and mani) people outside of my network could not connect, they say that they get:
1-Problems with connection.
Or
2-They are stuck on the parsing game info and then they are dropped.
I disabled the plugins and they tried it again but they got the same results...

Well, I just hope someone will help me

Heres some info:
Server OS: Windows XP Professional x86
Processor: Intel Core2Duo E8400 3.00GHZ cache: 6mb
Ram: 3GB DDR2
Game: Counter Strike Source
Startup Command: -console -game cstrike -maxplayers 12 +map de_dust2 -port 27015 -tickrate 100 -autoupdate
Admin Mods: Metamod and Mani admin plugins

If theres something missing, let me know.

What is the error they are getting? What is your server IP address?

[rp42]

They just lost connection, they try to connect but they can't...
External IP: 84.90.103.196
It passed trough a router, I already opened the ports
(27000-27050 TCP,UDP)
(4380-4380 TCP,UDP)
And yes, they try to connect trough the external IP

Nevermind, I fixed it, I went into the routers control panel and made a DMZ connection. Thanks for the help anyway guys ^^
