Hello.
I create this thread because when I try to open my cs2d server (cs2d_dedicated). It doesn't appear in the server list.

* I opened the ports but my Modem-Router is a MediaAccess TG588v and I don't know if I opened the ports correctly or if this Modem-Router only open ports in lan.

* Firewall is all ok.

I recommend to consult the manual of your router. Make sure that you forwarded the ports correctly. It's the most common problem when hosting a server behind a router.

This doesn't help. I don't know the router model you're using and how to configure it. It is possible that you need to configure more things.

@ DC:

I could open the server.
IP and other configurations were wrong haha

(Sorry for my english. Almost two years ago i started english school)

Okay cool! Glad to hear that it works now
