hi i dont no if a bug or what but the only way to work transparent my squid is edit squid.conf and add transparent to http_port 192.168.1.1:3128 if set transparent in web page the pfsense write in squid.conf http_port 127.0.0.1 transparent and no work only work by manual edit squid.conf
squid2 is working without problems on pfsense 2.0.1 in transparent mode.
what version of pfsense are you using ?
which squid are you using ?
did you select you LAN interface on squid GUI and did you select "transparent" on squid ?
did you enable the firewalol to allow traffic ?
