Cannot reach mozilla.org through proxy

You are probably right. As I want to block all HTTPS not going through the proxy (which is what rule 7 is for, if activated), there is no need to allow HTTPS again in another rule.

Hm, but enabling rule 7 thus far seems to be the only thing that blocks non-proxied HTTPS for me. My goal is that no HTTPS can be used without the proxy’s url filter. Are you saying my default forward communication setting should already be blocking HTTPS?

So you are saying, I should make the firewall rules more restrictive? Which rules are you referring to in particular? Again: it was not me who set up this firewall and I am quite new to the subject matter…

In my other post I have been warned to

So which one would you recommend?

Thanks again!
