Mirkotik are L7 rules correct?

Question

Mikrotik

Greetings! To block unwanted sites, I use this regular expression to mark DNS queries.

/ip firewall layer7-protocol
add name=badsites regexp="^.+(vk.com|fb.com|ok.ru).*\$"

The specified domains are successfully blocked, but along with them are domains that end in the same characters, for example: vo vk.com , htmlbo ok.ru . In theory, the problem should have been solved by replacing ^.+(with ^(, but no. Then the blocking stops working altogether.
I would be grateful for a hint on how to correctly compose a regular season?

Answer 1

Try this.^https\?://(www.)\?(vk.com|fb.com|ok.ru).*\$

Answer 2

Not the best solution, l7 percent is eating up noticeably. It's easier to add static dns records to unwanted domains pointing to 127.0.0.1.
