Ask someone on site for help.
This fiber router is a gateway. Through it, every computer on this local network comes to light. The address of this router must be provided in the configuration of the computer's network card. When you want to enter www.XYZ.pl, the data is first sent to this gateway (router), and it also sends it to the next one. If the configuration of the computer's network card directs traffic to, for example, the printer's IP for any reason, then of course "the internet will not work". Of course, you usually don't have to enter this gateway address manually in the configuration of the network card. You turn on the computer to the network, and the so-called DHCP server (running in this case on this router) gives your computer an address in the local network and tells you what the gateway address is. This happens automatically.
The same should happen with a VPN connection. This connection creates a virtual NIC (look at the screenshot you sent). There should also be a gate there. This gateway is physically some kind of router at the VPN provider. IA doesn't have the address of this gateway for some reason.
A 99% VPN connection changes the configuration so that all traffic stops sending to your physical NIC and only to the virtual NIC created by the VPN. But this network card does NOT have a gateway, an address through which the VPN's local network can go out into the world.
