This problem is caused by wrong firewall or router settings in 99% of all cases!
1. Configure your router (if you are using one)
Most routers have a web interface which can be accessed with your browser.
A common address for it is
http://192.168.0.1.
However there are many routers which use other addresses.
Please check the manual of your router for details.
Contact the person who setup your router/internet if you need login data (or check the manual for defaults).
What you have to setup is
port-forwarding. CS2D uses the
UDP protcol and
UDP Port 36963
Unfortunately we can't provide information here how it works because it depends on your router.
So please either read the manual of your router or try to get info from the internet.
For example at
www.portforward.com
As alternative you can activate the
DMZ Host option if you don't manage to setup port-forwarding properly.
However this is a security risk and not recommended unless you are using a good software firewall.
2. Configure your firewall(s)
Make sure your firewall allows CS2D to access the internet!
You have to grant full internet access (incoming and outgoing) for
CounterStrike2D.exe and - if possible - allow all traffic on
UDP Port 36963!
Also make sure that Windows Firewall doesn't block CS2D! Read the
Windows Firewall article at Wikipedia!
3. Further problems and information
- Do not try to play CS2D when using a proxy. It will probably not work or it will be too slow
- Make sure that
"Offline/LAN" (
sv_lan) is DISABLED (0) when you're running a server
- Make sure that you see the IP of your server in the
CS2D serverlist
- Restart your server/pc (not just CS2D) completely if your server's IP does NOT appear in the serverlist
- Port 36963 is default. You can also configure everything for another port and use this port for your server
