Hey, On http://www.freebsd.org/doc/handbook/firewalls-ipf.html there is: "For a detailed explanation of the legacy rules processing method, refer to http://coombs.anu.edu.au/~avalon/ip-filter.html." That link is redirected to http://asiapacific.anu.edu.au/ and has been for the last week that I have tested it. Yours sincerely Patrick
