Through mikrotik does not go to some sites?

Question

Mikrotik

Good day. There is such a situation that some sites, for example 2ip.ru and some others, do not open. That is, the browser seems to enter the site, but just a white window, and no errors, nothing. Everything else works. Even if you can tell me some kind of man in Russian. Where the same nat rules would be written.
Thanks in advance.

Answer 1

2ip.ru and some others redirect from port 80 to 443, it seems to me that port 443 is published (forwarded) without specifying the interface from which DstNAT should be done.
Disable all DstNAT rules if any. And check again.

Answer 2

If you do as in the previous answer, you will lose port forwarding (and this is Skype and various p2p clients, file sharing), so it’s better to study the Internet more closely for more specific rules that allow outgoing requests on port 80 (TCP).
