How can you fix routers so you can host games?

Do you enough bandwith to host games? Your upload speed needs to be pretty significant depending on game to be hosted.

well i used to run cs server off my cable line back home...it can be done. Make sure to run your server in DMZ mode that will mean its virtually outside teh firewall and so there should be no connection problems.

You just need to make sure port forwarding is set up correctly (put simply, so that the router knows which PC to send incoming game data to). To do this you'll need to know the ports the game uses to host and add these to your router's configuration along with the host PC's IP, usually via http or telnet depending on the router.

Before you go ahead with all that, you can try setting the host up as the default machine or DMZ. Assuming your router isnt already forwarding to other PCs, setting the host up as the default recipient of incoming data will essentially be the same as a direct connection to the internet, but it's the most clumsy and least secure way of doing things, effectively eliminating any security benefits of a router. DMZ options are normally alongside port forwarding options in the router configuration.

Have a look here for a description of the principles and technologies, and the differences between forwarding and using a DMZ.

In either case, you'll almost certainly need your host PC to be using a static IP rather than a dynamic via DHCP, which you can do in TCP/IP properties. The static IP you set should be outside of the range of the ones the DHCP server uses (usually that means the last number must be >32, ie 192.168.0.40).

If you need any of this in any more detail, tell us what router you have, it's LAN IP if possible and the game you're trying to get working.

I have Belkin router, and I am trying to run Joint Operations, an online first person shooter. I just really need to know jow to access the router configuration. When I host, or when my buddies host, we always have the same problem. We cannot seem to connect to eachother. In the game in question we get the error, enumerating session, whenever we create the game. The game is created just fine, and they have no trouble finding it. We aren't sure if it is a problem on my end or his, but it happens everytime we try to connect over TCP/IP connections on this or any other game that supports that sort of connection. I would appreciate any help you can give, and what you have given so far has been very helpful.
