I can join online or LAN games, but I can't host them

[yahsafaa]

In a LAN game like COD: World at War, me and my friend have set up a hamachi network to play LAN together. When I try to host, he cannot see me but when when he hosts, I can see his game.

We have also tried this on Rainbow 6: Vegas 2.

PS: I have tried it with other friends on other games but the problem seems to be on my side.

if they can ping, then it's ok. try to disable any other network interface on the desktop, keep only the LAN interface used in your setup. Otherwise, CS can expose the server to other interface.

I don't think it's needed, but you can check IP configuration by running in cmd: ipconfig /all. Make sure both your desktop use the same configuration (only IP addresses should differ). As I said, pinging ok is a good sign that desktop and latpop "see" each other at IP level.

One other thing is to check the port availability. Before you start CS on your desktop, make sure port 27015 is not used (you can verify with cmd command: netstat -an). After you start the server, this port should be LISTENING.

I can ping my friend, an also I have disabled other networks. Also the port 27015 does not appear when I type netstat an but other ports appear

disable the firewall (Windows or third-party), check the IP configuration, make sure you can ping all the host in your LAN etc.
the problem may be caused by the higher priority route of hamachi interface. if is that the case you can solve the issue by giving lower priority in routing table, but if you are not confident about this, better just use the disable interface solution.
Hope this was helpful
