Allow WoW updates

[jcoehoorn]

Here's the deal - I want to block the 6881 - 6999 port range, as it's commonly used for p2p bittorrent... except for World of Warcraft updates. The problem is that the WoW updates are themselves bittorrent data.

This would be easy to do by correctly ordering firewall rules to first pass the WoW traffic by port and IP and the deny the port range for any IP -- if only I could narrow the IP range used for the updates. Unfortunately, the nature of the bittorrent protocol used for this is to distribute the load among the many peers and so there's no simple IP range I can use to filter this traffic.

My hope is that surely Blizzard will provide full seeds that I can restrict to. Has anyone been able to do this successfully?

well couldnt you just make a bypass rule for the ip of the one machine that needs to download the updates?

There's no way to do what he wants as WOW uses BT for it's updates...you can bypass the one box yes..but otherwise there's not way to filter out only certain BT traffic..

@proactivens - we have many students who play WoW. It's not just one box.

I'm hoping to pass traffic on those ports for the IPs of the original blizzard seeds only. I think that should still work, just not be as fast.
