my costumer´s Internet Firewall between inside, outside and DMZ networks is a Linux running Iptables. Well, his Proxy Server is installed in DMZ network and his inside workstations access webpages passing through this proxy. This access is carried through of transparent mode, therefore in these same machines do not have proxy configured in the web browser.when a solicitation passes through firewall come of the inside network, iptables can get all these traffic and to direct for the IP of proxy and in the door where this is hearing, being thus, all solicitation for Internet obligatorily passes for this.
Well, can I do this using PIX Firewall? I want to take off this Linux Firewall but I need to guarantee that the PIX will make this exactly service.
The PIX won't redirect all HTTP traffic coming through it to a specific proxy server sitting on another interface. Why does he need the proxy server, if you put a firewall in then you can usually get rid of this device and just have your users go straight out to the Internet.
