Good it worked when I added rule in Mangle too. All other ways were not enough to block website. Thanks

This is really nice and useful,

I want to block the Internet except few website. I mean only few website will be allowed for Whole Subnet or specific IP.
I already applied one filter rules, Some website's is blocked by MANGLE rules. Now I can't stop the Internet Access for all.

Thanks for the tutorial, It works! but when i try to allow facebook for a specific user it doesn't work, mikrotik block facebook for all users though i put the accept rule on the top of the reject rule. Can you please make a video how to block all website except facebook or any other specific website?

[amontep]

why are you mark traffic before blocking it? is it possible after defining the regex to go directly to filter to block the traffic without first marking it?

[Ojnabanjo]

Hi, I follow and watch all your videos when setting up our mikrotik router so far so good. but this tutorial didn't work me is there a newer way of blocking facebook? (posting this 3 years after the video )

[ElfofTheNight]

Hi, thanks for the video you shared, I found that the website blocking failed, some characters in Regexp could not be displayed properly，For example: the characters displayed by keyboard shift+6 are wrong

[Martin-otxj]

Hi there, please make a tutorial video about which dengrous ports list by default we must to block on microtik firewall. Thnx

[sebastianmangelsen]

I think the mangle rule can be further improved by setting "connection-state=new" otherwise the very expensive L7 regexp function would be executed for each and every packet. What do you think?

[bhartendulal]

Hi sir, thank you for video, I want to ask, sometime after rule applied, it pass the packet very lately, i use the same rule as you tell in the video, but first 5 to 10 minutes it doesn't work, after 10 minutes, i see the one packet pass then rule start to work as configured, , , May i know? why the rule start to work lately?

[sollekram]

If you want to redirect them to an other page?

[jngweji]

Hello Sir Does the rule also block Facebook when accessing it from Facebook Application installed on Android or it only blocks users accessing it from the browser?

[aminullahrasooly]

It doesn't in android facebook apps but in messenger it does work, any update plz !
