Can I access the router's admin panel by connecting to a vpn or proxy?

Question

VPN

Hello, I want to raise my vpn server or proxy, but I need to be able to connect to it and go to the admin panel of the router, is this possible? if so, do I need to do something else or just connect to the VPN and at the address 192.168.1.1 I will go to the settings of the router (which broadcasts the VPN) and not to the settings of my router. And if you buy a router with a built-in vpn server function, will it be possible.
