The squid and pfsense in new for me. I installed the Packages squid and squidGuard to the pfsense and i enable Transparent proxy from Proxy server and the Proxy filter. It works correctly, it block my blacklist. But it is a few sites which is not in my blacklist and could not be retrieved. I got the following message from browser:
Any idea who to "unblock" these sites?
I find the solution, the sites i got the massage was host in my vpn network and i should check the option "Disable DNS Rebinding Checks" at menu System->Advanced->Admin Access
