Good afternoon. Faced with a problem that occurs in my mikrotik not open some sites, namely http://www.tutu.ru/, http://www.airfrance.ru/. If you connect a laptop on the line directly to the provider works. Do not know which way to dig, ask for help. Ppp connections of any present, get from an external provider ip once the first ethernet port.

1) Check "Change TCP MSS" at your PPP profile (should be "yes")
2) Then check it is correctly applied at IP > Firewall > Mangle after PPP call

Thank you, but I just do not "PPP" connection, and "Ethernet", after a reset to default router, sites began to open, the problem did not manage to locate.

There was another problem with another router in another office.
Do not let one site https://booking.utair.ru, although others are let for example https://google.com, https://mail.ru. What could be the problem?

now is not working https://qiwi.ru/, logs or tell what information should I provide to you that you could understand my problem. Thank U.

Sometimes sites are really unavailable, an ISP have problems with its channels or you are simply banned etc.

From your screenshot it seems the default config works pretty well.

You have to isolate your problem, noone can help you with such poor info.

And check your ISP btw (http://deem.ru/ip/).
