Ah, ok. You'll want to specify two allowedip ranges on the clients, 192.168.178.0/24 for your network, and 10.0.0.0/24 for the other clients. Then your going to need to add a couple of routes:
- On the phone, a route to 192.168.178.0/24 via the wireguard address of your home server
- On your home network router, a route to 10.0.0.0/24 via the local address of the machine that is connected to the wireguard vpn. (Unless it's your router/gateway that is connected)
You'll also need to ensure IP forwarding is enabled on both the VPS and your home machine.
Which is why you end the fight before it starts. The greentext got lucky but by reacting oddly enough to make the robber pause then leaving they did the right thing.
I've been in a similar situation except I punched the thief before they drew the knike and then left. The fact he was obviously high as a kite probably helped. Ultimately, a knife fight between two sober, focused opponents, who are intending to kill or seriously injure will likely end as you suggested, but it the aggressor isn't actually ready to fight the fight can be avoided, or ends up much less lethal.
