Are you trying to block traffic originating on machine with PF and Squid or is this machine firewall for LAN? I think you need to add port www (or port {80, 443}) to your rdr rule and also specify on which interface you want to do this translation. If you need to filter traffic from your LAN to outside world you need to specify LAN interface. Something like this rdr on $int_if inet proto tcp from any to any port www -> 127.0.0.1 port 3128 pass in on $int_if inet proto tcp from any to 127.0.0.1 port 3128 keep state pass out on $ext_if inet proto tcp from any to any port www keep state More resources can be found here http://serverfault.com/questions/490926/freebsd-pf-squid-transparent http://www.benzedrine.ch/transquid.html https://forums.freebsd.org/threads/10874/ Miroslav Lachman
