Hi,

What I've had success with is using policy-based routing, selecting the routing table to use based on UID's.
You create a new routing table for the WireGuard VPN and add a rule directing that users traffic to that table.

Using commands you can do this to route traffic from the user with UID 1000 to table 500.
> ip rule add pref 20 uidrange 1000-1000 lookup 500

You can also do this in systemd-networkd if you're using that. Not sure about other network managers.

Best Regards
Nils
