We have ours behind so the squid server gets the protection of the firewall. We then use the firewall for transparent proxing of requests. That is, we don't let anything go out port 80 unless the request is from squid server. All traffic destined for port 80 is then redirected to the squid server/port. -----Original Message----- From: donovan [mailto:donovan@xxxxxxxxxxxxxx] Sent: Tuesday, August 08, 2006 6:57 AM To: squid-users@xxxxxxxxxxxxxxx Subject: place squid before or after firewall greetings I have a new cisco pix 525 and i would like to setup squid / squidguard for transparent filtering.
