My WireGuard Setup

[Spidermila]

Using gateway=10.254.254.x can be in fact slightly confusing, even though it’s correct. But you can’t do dst-address=192.168.150.0/24 gateway=10.254.254.4 (wrong gateway, belongs to different peer), which is obvious, but maybe not to everyone, so if it’s simple config like this, I’d probably use gateway=. With some more complex config, e.g. if you’d have alternative route to target subnet and you’d need WG route with check-gateway=ping, then address would be required.

OK I have removed it for simplicity. Original post updated.
Thanks!
