Hi,

I'm looking for a way to allow connections to computers in a LAN while a Wireguard tunnel is active.

I know this is probably extremely easy but, unironically, I can't find an actual guide on how to do it. I'm using the default "wireguard-tools" which I installed using

sudo dnf install wireguard-tools

And then something called Wireguird to set up the tunnels. The OS is Fedora Workstation 43.

For the tunnel and keys I signed up for the Proton VPN service which has its own guide on how to set it up with Wireguard.

My problem is whenever the tunnel is active I can only access the internet, and the rest of the LAN is cut off, for example I'm not able to connect to a file server, use LAN Messenger, or see things like scanners or printers.

Is there a way to do both at once? problem is my internet is extremely slow and it takes its sweet time to open even the least bloated websites, and hours to download a file IF it's stable and the download isn't cut.

I read I need a special router to do that, that can't be truth, right? there's no way to get "high end" routers in my country and all I have is an ancient ISP modem wired to a probably equally older Cisco router.

Thanks.
