how to break through the firewall?

I have tried to use sockets to send a message along the port that I am using but that interferes with the GNET_LISTEN command
I also tried to use GNET_CONNECT with the host of the game to see if that opens the port but no success.
I can only play online if the host PC has no firewall, otherwise it doesnt recognize connections.

Two solutions:

1. Use port forwarding.
2. Use UPnP.

hmm pretty complicated stuff
port forwarding is just for routers right?

Is the firewall on the host PC, or a separate device between the client and host PCs?

If it's on the host PC, when the app is fired up on that end, most software firewalls should prompt you about opening the port. If it's a separate device, you'll need to open a port on that device, or pick a port that is already allowed through that device.

I was using a laptop that is connected to a wireless network,


I just tested it with windows firewall only...it works!

so its just the wireless network router giving problems

Yeah, then what Gfk said about the port forwarding should work.
