You don't need to allow ALL UDP packets. Find a couple of sample ipfw configurations in the archives, they've been posted a number of times, and look at those. Adding a "cache only" DNS server on your FreeBSD machine and having your Windows machine use that as it's nameserver will potentially save some DNS traffic (and latency) for you. -- "Where am I, and what am I doing in this handbasket?"
