I’m having trouble getting Dawn of War II to sign in to Windows Live when the Comodo Firewall is enabled. It times out saying unable to connect.
When I disable the firewall it works fine. I checked and both Dow2.exe and GFWLclient.exe have policy set as:
Allow IP In/Out From MAC Any to MAC Any Where Protocol is Any
Using smartsniff, I noticed that when firewall is active, there does not seem to be communication to the 3074 port, while with firewall disabled, there is traffic.
Firewall does not prompt me to permit traffic nor does the log show any blocked traffic.
Any ideas?
You also need to open port 3074 in Global Rules.
Read the following tutorial I made. Substitute the port numbers and protocol for your situation.
To open the port TCP 1723 for example
First step is to determine the MAC or Physical address of you network connector. Go to Start → Run → cmd → enter → a black box will show up and enter the following → ipconfig /all (notice the space before /all) → enter → now look up the Physical address and write it down.
Notice that Physical address = MAC address
Firewall → Network Security policy → Global Rules → Add → fill in the following:
Action: Allow
Protocol: TCP
Direction: In
Description: Incoming Port
Source address: Any
Destination Address: Choose MAC address and fill in the found MAC/Physical address
Source Port: Any
Destination Port: 1723
Then push Apply → Now make sure that the new rule is somewhere above the basic block rule(s) as the bottom (the block rules have red icons); you can drag and drop the rules → Ok.
Unfortunately that did not help.
I tried creating a rule which would parmit TCP & UDP traffic in and out from any MAC to any MAC, and that did not work. Creating a rule to Allow IP In/Out From MAC Any to MAC Any Where Protocl is Any did not work either. Nor did setting the firewall to Training mode.
So far only thing that works is disabling the firewall. Really strange.
Can you show a screenshot of Global Rules?
I tried creating a rule which would parmit TCP & UDP traffic in and out from any MAC to any MAC, and that did not work.
When making rules for a specific port in Global Rules you need to make separate rules for incoming and outgoing traffic. Making a rule for TCP/UDP In/Out will not give the needed results. For most applications an allow out going traffic suffices though. In your case that would mean making a rule for incoming should be enough
Creating a rule to Allow IP In/Out From MAC Any to MAC Any Where Protocl is Any did not work either. Nor did setting the firewall to Training mode.
Training Mode does not allow unsolicited incoming traffic.

Do you have other security programs running in the back ground at the same time or programs running that interfere with networking (Netlimiter, Peerblock etc)? See if disabling fixed it or not/
I tried the attached sets of rules.
I had NetBalancer installed on the computer. I have now removed it, but that did not help.

I’ve been having GFWL problems in Dirt 3, and NONE of the suggestions I found online worked, including Comodo’s own forums!
But once I disabled “Block Fragmented IP datagrams” in Advanced tab under “Firewall Behavior Settings”, everything works just fine.
Comodo should do something about it, because they scare you saying something like “You MUST NOT disable it, or else the whole world will come to an end” or something like that. 
I hope it helps others with Games for Windows issues.
Cheers…
Thank you for informing us.
“Block Fragemented IP datagrams” is disabled since v5.8 IIRC. It gave too much problems to have it enabled by default.
Well, since your update does not work (discussed under other threads), and your web site does not indicate the current version number (for downloads) either, this is the version I have.
