I have trouble with verifying my cd key for online play and I checked the sticky for this and I have a question about it, for the ubisoft service thing, do I really need to open all the 3000 ports for it?

"UBI.com ports:

TCP: 40000 - 42999
UDP: 41005"

It's waaay too much of a security threat for me to dare open then.

Using vista 64bit, window's firewall and a netgear router.
