I’m familiar to use dynamic routing and not static routing. All tutorials are with static routing where wireguard is included.
First i tried to add the routing and then disable the routing in the same command. Like this:
PostUp = ip route delete 192.168.5.0/24 dev wg0; ip route delete 192.168.6.0/24 dev wg0
PostDown = sleep 2
Then i found a way to disable the complete manual routing with this syntax in the wireguard config file.
Table = off
