NordVPN on Windows has a feature called 'Invisibility on LAN', which, if disabled, allows the device connected to the VPN to still be discovered by other devices on the local network.
When this feature is enabled, the device is not visibile on the local network, and you can't access things such as your router page.
It seems that, by default, my Ubuntu computer, while connected to VPN, is not discoverable on the local network, and as such, I can't access my router or any local devices. In the settings, I also can't see any option called 'Invisibility on LAN' or with a similar name.
How can I make my computer discoverable on the local network, but still be connected to the VPN while acessing the internet, like I can on Windows?
