I want to setup a firewall (ipfw) on my freebsd 4.8 p3 server. The machine runs web, ftp, ssh, dns, smtp, and imap to the outside world. Does anyone have any links to example rules for servers? (I've already looked at the handbook and man file)

My problem lies in UDP rules. I think I have TCP figured out. My first attempt blocked off DNS queries from the machine outward. I could query the DNS server, but apps could not do lookups. i figure it has something to do with ports above 1024, but I'm not sure how to define a rule with multi ports in a range, plus I don't know how high to go above 1024. Is this the right action? Ideas on syntax?
