How to block web site, simple step by step
-
@andrzejls in the resolver (unbound)

@johnpoz Great, thanks. Now I know where to go, but still I can acces that web site. Should I reboot pfsense, clear Brave cache?.
-
@andrzejls and again - clients have their own cache.. Clear the clients dns cache, on windows that can be done with ipconfig /flushdns, also browsers run their own cache as well.
No you would not need to reboot pfsense.
Do a query for cnn.com - do you get what IP you put in 0.0.0.0 or 127.0.0.1?
Keep in mind also if your actually using the proxy - the proxy is going there for your client and the client is not doing any dns for cnn.com..
-
@johnpoz I still can access web page. Maybe it is me but It seams strange that pfSense being such a powerfull firewall that is is so difficult to block individual web pages.

It is not difficult - its childs play really with the tools that pfsense provides. But not understanding the tools and how they work, then sure it difficult trying to use a tool you do not understand.
You could block via pfblocker with couple different methods, you could sure block with proxy, or you could just block with simple dns. You could also block via just firewall rules to what IPs you want to block, etc. And you could even just have pfsense resolve some fqdn, and use that IP(s) in a firewall rule.
You could give a cave man a tricoder from star trek - do you think he would be able to use it?
I gave you the simpliest way I can think of to block a domain that has IPs that change, and has multiple IPs.. You just need to use a client that uses pfsense for its dns, and isn't using doh in its browser, etc.. Or using a proxy..
First step - if you setup your domain like I showed in unbound - do a query from your client using nslookup, dig, host - your fav dns tool.. Does it return the blocking IP you put in? If not then your client isn't using pfsense for dns, or you didn't setup unbound correctly to return that IP for that fqdn..

You are 100% correct. That is the reason I ask. I removed "squid" so I only run pfblockerNG and "snort"
Here are my "custom options:
-
@andrzejls ok that looks ok even if your loading the pfblocker.conf
So do a query to unbound on pfsense.. Does it return 0.0.0.0 like my examples.
If not - then your client is not using pfsense for dns and can still get to cnn.com, maybe your browser is using doh (dns over http) many browsers love to do that on their own, etc.
Or your local browser or os has the IP of cnn.com still cached.

@johnpoz You were right on the money. My Linux laptop Brave browser was set to use 1.1.1.1 DNS. Once I changed that to pfSense IP it works. Thanks for your assistance, patience and understanding my lack of knowledge on this subject.
-
@andrzejls glad you got it sorted.. btw your not really blocking cnn.com are you ;) hehe I take it that is just some test you doing on how to block a site..
-
@johnpoz Of course, it is just a "test" :) hahaha. I am also testing cbs,nbc, and other main stream media.
