I’m paying for a VPN service that has a limited number of concurrent devices but I want to use it on all of my devices. Is there a way to self-host a Wireguard VPN on my Linux server that will forward all WAN traffic to my third-party VPN provider? Ideally, I would generate a Wireguard config for this gateway, and all my devices would connect to my local VPN gateway server, thus allowing me to share that one config across all devices.

My router does not support VPN configuration and modifying its firmware is not an option.
