I am trying to have a game over the TCP/IP but neither my opponent nor I seem to be able to connect to the other's computer.

We used the IP address that CMBO gives us and I also tried the IP address that i got from www.whatismyipaddress.com.

So any advice how we can get connected?

I am not a tech guru so if you can help me in simple layman's words it would help!

Thanks!

You have firewall, routers?

Describe how the both of you connect to the Internet.

You can use this to securely find your real IP address.

As given, this commandline also does a portscan back to your machine to see whether the CM ports is open. (Don't complain to me that I scan your computer :)).

Yikes...the applet didn't work! :-(
I am not sure what a commandline is...i know i am a tech idiot!
I connect to the internet via satelite.
thanks for trying to help me out...what should i do now?

Well, the applet might not work, but there should still be a portscan line.

If not, posty your IP and I scan manually.

EDIT: never mind, I got it.

You have a firewall active, something is blocking port 7023. Unblock it. If you use a router you also need to forward the port.

errr...how do I unblock a port? I don't think i have a seperate router.
thanks again!

I don't use Windows for my Internet connection so I don't really know, but open the network configuration dialog and select TCP/Ip for your Ethernet card (or whereever your sat hardware is connected to).

You will also need to figure out whether you actually have no router. Your sat thingy might very well be one.

Look up the IP address on the Internet in Windoze and see whether it is the same as reported on the Internet.

Also, remember that certain LAN fast lane connections use 'packets' of fast info, this means anything that wants to be smoothly streamlined can become jolty, or even a dud!
I didnt get wether your game was turn based or a 'realtime' game so...

CM uses only one straight TCP connection, no out-of-band data within that connection and no secondary connection.

Hosting a CM games requires nothing more than port 7023 visible from the internet, which means firewall off on that port and forwarding if you have a masquarading/NAT router.
