squidGuard - Unable to change IP for sgerror.php URL in configuration
There is an issue with squidGuard where a user is not able to specify the address that squidGuard provides the client machine on the event that a page has been blocked. If said address differs from the LAN IP on port 80, you are not able to serve errors to users.
(For example in the situation where there is a network being filtered with users on it that differs to the LAN, and you do not wish to have a route through, the error pages do not work). Can be fixed by editing config file but these are reset on reboot.
