Hi,
I'm currently living in Vietnam and trying to launch a game with my brother in France. But we are unable to start a multiplayer TCP/IP game. When I check my IP with whatsmyip.com, i have something like 117.5....., but C&C multiplayer screen always put something like 192.168.... I believe that the issue is linked with router/firewall. Does anybody has an idea on how to solve the problem ?

ou must make sure your Firewall(s) is allowing CoI to access the internet

CoI Ports  to forward to your 192.168.... address

2300 to 2400 udp/TCP
6073 TCP
47624 TCP

I'm having the same difficulty - only seeing my internal IP address. When I search for games I get a blank roster, then a text message at the bootom saying 'Searching subnet', then a blank roster & my Internal IP -

I've tried forwarding the ports mentioned above - "CoI Ports to forward to your 192.168.... address" -- silly question but I'm a dummy with these things --

My internal IP is 192.168.2.2 & my default gateway is 192.168.2.1 - which one am I forwarding the ports to in the router?

Any help appreciated....

Another dumby question - in the roster should I be seeing a list of games publicly hosted on the net or do I have to know the IP address first before I can see anything on the list? Tried looking on Gamespy (my usual last ditch resort to get round my router) and although Close Combat IV is listed there's no Modern Tactics ... is there ANYONE playing this game? Help!

You  have to know the IP address first.

Thanks for the reply - any idea about the address to forward in the router? - is it the default gateway or the IP of my machine on the LAN? Cheers!

You have to forward the ports to the IP of your machine on your LAN.

Below are the ports


CoI Ports
2300 to 2400 udp/TCP
6073 TCP
47624 TCP


For MMCCIII

Ports 1939 to 1945 and 2108 to 2110 must be open/forwarded in your router/modem for this app. to function correctly.

I have a problem. I forwarded ports for my router, but I still get only internal IP when trying to host multiplayer. Any idea what went wrong?

Do you have your firewall set to allow CCMT?.... In both your PC and your router?

but I still get only internal IP when trying to host multiplayer

Do you mean your internal IP address is displayed on the mutiplayer screen... that is normal even though your external IP talks to the world and any data using the listed ports gets redirected (forwarded) to your internal IP.


You can find the IP address you want to give to your opponent here:

http://whatismyipaddress.com/

The manual says that the multiplayer screen should display both my internal IP and the external one.

Try this

Launch CCMT

Play a multiplayer game

On the multiplayer screen selct "HosT"
 
Your IP should pop up in the bottom left hand corner of the screen

Alt-TAB out of CCMT

open this page in your browser :  http://www.canyouseeme.org/

Type 2300 into the box ... if you are forwarding correctly you should have "success"

Then try 47624  again you should have success if you are forwarding correctly and you have your firewall(s) open.

Thanks. It seems that they are correctly forwarding

Hmm...
I have a question.
If I have modded base data (only .txt files), then if I'll host a game, will those that join be able to play the modded game with me or would they have to download the mod first?

I disabled my firewall which I have with bitdefender and disabled the privacy control as well. Went to the canyouseeme.org website and typed 2300 into the box and got the following message:

Error: I could not see your service on 71.55.219.198 on port (2300)
Reason: Connection refused

Am I missing something which needs to be turned off or tweaked? [&:]

Thanks. [:(]

OK. This is what my router screen looks like in the Port Range Forward screen. What do I enter into the fields to open the right ports and such for multiplayer?

application = CoI

Start = 2300
End = 2400
Both = correct
Ip Address 192.168.1.****

\start\run\cmd    this will open a dos window
type ipconfig and press enter


where it says IP Address that is what you put in the box



Do the same for......47624

start = 47624
end = 47624

Tick enable on both

So is that all I enter in the Application field just CoI? I don't type CoI.exe or anything like that?

Thanks.

It's only a text file so you will know in 5 years what the port forward was for

5 years? [&:]

It's just a reference so you will remember what it was for ...in the future... 1 day or 20 years.

I have a new problem. When I host a game, I can't proceed to battlegroup screen from oporder screen. I don't know what to do. The "next" button is grayed out. The second player can proceed to the battlegroup screen...
