Block Port 80 Out from LAN

Configuration RecipesSetting up WPAD Autoconfigure for the Squid Package

Create a firewall rule at the TOP of the LAN tab (or appropriate interface) that blocks anything from <internal subnet>

to * on port 80.

Note: If the firewall is used to serve WPAD and the WebGUI anti-lockout rule has been disabled, web traffic must also be allowed to the AZTCO-FW firewall GUI port. If this is not acceptable, point wpad. to another internal web server which can answer requests for the wpad.dat and associated files.
