Ok. I have never step either a transparent or non-transparent so I want the easiest one to do. I have tried turning Transparent on in HTTP Proxy -> General, but it did nothing for it. Do I need to setup a port or anything for it. Sorry for asking so many questions, I just really want to get this working. Plus I have another friend locally that is trying to do the same and I can pass this information onto him.
Thanks
No, there is no need to set up a port. Just make sure the module is installed on your system, and that it is running (you can see it on the dashboard under "HTTP proxy").
In my case I have set it transparent, no need to configure the clients.
I have blocked out all social network and dating sites for some people on the network, using object policies. It does work as expected.
The proxy used in Zentyal is Squid, there is a lot of info about this on the web and it is also explained in the Zentyal documentation. You might want to read up on it.
Cheers.
