I have a pfSense box that I'd like to add squid to to use as a proxy that I can use remotely. I have installed squid, but I can't figure out what firewall or other settings I need to change to get it to work.
The only specific configuration I can think of is allowing any IP to connect to your squid proxy. In "Proxy server", you have the "Access control" tab. You can put 0.0.0.0/0 and see if that helps.
If it doesn't help, you're going to want to create a specific rule in your firewall to allow access to squid. This should look like allow any to squidIP on tcp squidport on interface WAN.
That should do the trick.
