PF e Squid trasparente

Le modifiche da fare al file di configurazione di squid sono minime:

http_port 127.0.0.1:3128
http_access deny to_localhost
acl our_networks src 10.0.0.0/8
http_access allow our_networks
visible_hostname proxy.mynet.org
httpd_accel_host virtual
httpd_accel_port 80
httpd_accel_with_proxy on
httpd_accel_uses_host_header on

mentre, per quanto riguarda pf:

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

Attenzione!

squid cerca di aprire /dev/pf per interrogare il packet filter. รจ necessario quindi assegnare i corretti permessi:

chgrp _squid /dev/pf
chmod g+rw /dev/pf
