Best Answer

Depends on what ports you open, and what kind of internet connection you are running. If you are running a residential internet connection, and you are doing your usual day-to-day things (email, web browsing, YouTube) then you should not have an issue opening ports 80, 25, 443 and whatever else you use. Though you should note that if you are doing more dangerous things on your connection (you know who you are ;) ) then you should probably not open these ports as they can be used for malicious things.

Compare the TCP header and the UDP header?

Both TCP and UDP have origin and destination ports - and that is about all the similarity there is between the two. TCP has several other fields that UDP doesn't have, including window size; a consecutive byte numbering (to figure out where to place a TCP segment in a data stream); the bytes that the other side is expected to send; and others.

If you're having problems connecting, make sure you've got the correct Router ports opened or triggered, both for the PS3 & PSN, and the specific MW2 ports as well.ROUTER NAT AND UPnP MODES - ENABLED*Note: Make sure to enable these TCP/UDP ports in BOTH directions (i.e, for Routers that have TCP, UDP, and Both for settings, set them to Both. If your Router doesn't have that type of setting, set the Port to either TCP or UDP as indicated, and enable the pass-through in both directions (full duplex))TCP Ports: 10070 - 10080 UDP Ports: 10070 Voice Chat: UDP 6000-7000, 10070 (for headset operation) Remote Play via Access Point: TCP 9293PLAYSTATION Network: TCP Ports: 80, 443, 5223 UDP Ports: 3478, 3479, 3658Call of Duty - MW2 Ports:TCP 27014-27050 UDP 1500, 3005, 3101, 27000-27030, 28960It's easier to use Port Range Forwarding or Triggering instead of Single Port Forwarding. In those cases where there isn't a range but only a single port listed, your range is the same port, e.g., Range 5223-5223 for Port 5223. Port Triggering is also preferable to Port Forwarding, since Triggering relies on the game or application in question to trigger the Port request when necessary to the Router. Static Port Forwarding setups keep your Ports open as long as they are enabled in the Router setting, and as such are more vulnerable. Trigger Ports are only open as long as the game or application needs them to be open.
