Battlefield 2 + Call Of Duty 2

Hi… I am new to comodo and dont really know that much about firewalls. I have 2 pc’s connected to a hub with 1 of them connecting to the internet. I also have comodo installed on the that connects to the net.
The other PC on my LAN is one i play games on. So i go through the other pc’s internet connection.
When i try and browse servers in the games i keep getting a ddos attack coming up in the comodo logs. Looks like this : http://[img=]

If anyone could help me on this matter i would be very grateful.
Thx in advance. Busta
