Hi list,
On a Linux system (Ubuntu), I would like to enable Wireguard VPN only
for a single user on my system.
Currently by default, every packet of every user is getting though
Wireguard.
How can I do to route packets only for 1 user ?
I think I have to play with packets marking (wg show wg0 fwmark /
iptables owner/mark module), I tried some commands but was unable to
success.
Can someone help please ?
Thank you.
Florent

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

Hi,
Thank you it works very well matching my excluded user and using "lookup
main" ;)
> ip rule add pref 20 uidrange 1001-1001 lookup main
I though it was more difficult and didn't know that "uid matching" in
"ip rule".
Thanks
