Kinetic Giga router not pinging Russian Railways website?

Question

Computer networks

I ran into a very strange problem.
A few days ago, all Russian Railways sites stopped opening for me: rzd.ru, ticket.rzd.ru and others. "Fuck" - I thought. Again, the Russian Railways are stirring up something.
On the third day, I thought that three days of lying for the site of such an office is strange. And I tried to open it from my phone via 3G. To my surprise, everything opened up.
Started digging. The site is not pinged from the computer. From the router too. At first I began to sin on the provider, but then I connected the ethernet cord directly, and it all worked.
What could be the problem?
Technical details:
- Provider - online (no connection settings, pure DHCP).
- Router - Zyxel Keenetic Giga. Firmware 1.4. There are no filters or tricks configured. Tried reloading. When pinging with a cord to the computer directly - everything is OK, when pinging from the router - 100% loss. "The rest of the internet" works.
- the trace to Russian Railways is somewhat strange and does not end in both cases (with and without a router):

Judging by the trace, Online has nothing to do with it. The trace reaches the MPS servers. Perhaps RZD messed up something in DNSs? But the main question remains: why does it open without a router, but not with a router? And what to do?

Answer 1

try replacing DHCP with Static IP, and in place of dns from the provider - drive in from Google and see what happens.

Answer 2

You can not change the settings to static, in many routers it is possible to set the dns settings yourself, since some do not know how or do not want to accept dns settings from the dhcp server. and just in case, compare the dns settings on your computer when you plug the cable into it directly, and the dns settings in the router when you connect through it
