I select the categories for filter, for example, violence, drugs, and porn, and the other options, so when I search a site with porn and entering the page, this content is not blocked, and I don’t understand this, because I follow the steps for create a filter for urls. How can we block content permanently?
I’m following the URL filter config and the Web proxy config but nothing seems to work.
Hi @zombi3, welcome.
In transparent proxy mode not work https. You must configure proxy in non-transparent mode.
After this, you have to make sure that all http and https traffic goes through the proxy by modifying in “Control Panel” the “internet options” → “connections” → “lan settings”. (in windows).
And finally, create a rule in the Firewall so that it discards all the requests that do not pass through the proxy so that they cannot bypass the protection.
If you search the forum, you will surely find more information on these topics. 
Greetings
I created these two rules. They must be put with this order!!! When one rule is valid, the following rules are not executed. This is the logic.
The first one “frees” a certain group of IP in my green.
The second blocks all traffic from GREEN to RED for all other IP. Automatically, all traffic that “goes through the proxy,” is not affected by this rule.
Big problem: In this way, only browsing is possible. All services that use other ports (POP3, WhatsApp, SMTP, FTP, … will not work, unless other rules are set to free the relevant ports).
Can this major problem be remedied?
Even acting on the protocol (changing ALL with the ports to be closed) creates another problem: If http(80) and https(443) porn sites use other ports (which is rare but possible), those are not blocked (if the traffic does not “go through the proxy”). I have to add rules for each list of ports to close.
And by the way, porn images displayed in search engines (google), are not filtered. (You need to block google).
The “Blocked Expressions” function, “the list of dirty words,” works only for http, but I could not integrate it for https.
I am convinced that there is no other remedy. If I am wrong please correct me.
