Can play L4D2 online.

Hey! Ive always had a problem with TF2. Atleast since I got my new PC last christmas. Basicly when I join a server I haven't played on earlier I can play for about 20 sec and then it's connection lost. Next time I join that specific server it's nemas problemas. And as I usually play on the same servers thats never been a problem. Til now.

Just got L4D2 and it's useless online. This time however it doesn't even matter if ive played before. Whatever I do either I get connection lost after a few second or as the campaign loads I'm returned to the lobby with a messege saying Connection lost.

This is infact quite annoying as the game is pretty much useless.

Any ideas as what the problem might be?

What is the router/firewall your running, and are the ports forwarded?

For forwarding your ports check out www.portforward.com.

In some cases an antivirus with firewall blocks access to the Internet. And can be solved by using 'learning' mode.

Thank you, I know nothing of networks, routers and similiar, all I know is that we have a router thats built in to the modem. Opening ports you say, I will try to get some knowledge of it. Although, how come it's only the source games that has this problem, and why mainly L4D2? And I do actually get in to the game most times, thats odd...

Well, thanks. Anymore tips maybe?

Hello there,

Each game depends on certain ports to run with Online Multiplayer, and they cannot be the same port because of listing the servers. I think it is a router/firewall issue.

Ports of Left 4 Dead 2 are:
Application: L4D2 External port: 88 Internal port: 88 Protocol: UDP
Application: L4D2A External port: 3074 Internal port: 3074 Protocol: TCP/UDP

Make sure they are open...

About your router:
Go to your router and check what kind it is for example: WRT610N

Search for it on www.portforward.com and follow its steps.

How they explain it every one can do it. It is quite late for me right now. I will heads up tomorrow early when I wake up.

Regards,
Darkened

I don't get what you mean by;

Application: L4D2A External port: 3074 Internal port: 3074 Protocol: TCP/UDP

Which one? TCP or UDP?

Haha heres something easier.

Go to your firewall or antivirus, and add the game to your exceptions list and add steam to it as well.

If you dont know how to do that, go into google and type:

How do I add programs to exceptions for (your antivirus name) and you will find how easily.

He doesn't have a fire wall problem bud, it's a port problem.
