Why does a computer with linux in a corporate network not open all sites?

Question

linux

Description of the problem: ubuntu is installed on one computer, network settings via DHCP. Browsers do not open all sites. For example, teamviewer.com, mirror.yandex.ru. And they don't even ping. And with win-wheelbarrows it opens without problems. Prescribing statics on the network card of a computer with ubuntu and other linux distributions does not help, but there are no problems when connecting a provider cable directly to ubuntu or prescribing a free proxy. There is a network with the domain. AD, DHCP, DNS (I once raised it myself). The settings are simple. Provider TTK-Volga (static). The cable from the provider is connected to the server, from the server via the second network card to the wi-fi point. QUESTION: Tell me what settings to look at in the domain (or in ubuntu) to solve the problem.

Answer 1

See the tracers, if the IP resolves, then the problem is somewhere in the transport. On which hop it breaks, there is a problem.
Those. if the route does not start at all, the problem is local on the PC, if it breaks on the gateway, then pick it.
Although there are many options.

Answer 2

Does the domain name resolve to the address?
If not, see DNS.

Answer 3

Your question already has an answer.
The problem is in the router settings. See configs. Perhaps someone played a trick on you by creating a rule by MAC or IP address.
