Squid transparent proxy blocks all HTTP traffic
I've seen others having similar issues on the forums, but I've not seen any definitive answers that work… I'm running 2.2.6 nano on Watchguard firewall. It's working pretty well, but when I try to setup squid3 (or 2) as a transparent proxy suddenly all HTTP traffic is blocked (HTTPS still works). As soon as I disable the tranparent proxy everything works again. I can setup a non-transparent proxy and it works correctly.
Has anyone solved this?
…something I forgot to mention...not sure if it's relevant. I have one port setup as WAN and I have three ports assigned to a bridge for my LAN. When I setup the transparent proxy, I'm binding it to the LAN bridge.
Some more info…
The proxy seems to work fine (normal and transparent) if I set the proxy settings in my browser. However, if I have transparent proxy enabled and remove the proxy settings from my browser, that's when I can't browse any more.
It seems like the requests just aren't being routed properly. How is the routing through the transparent proxy done?
