Re: How ca I use two peers with 0.0.0.0?

Hey!

There's multiple ways to achieve this, each with its own set of drawbacks.
Firstly though, the reason why this is impossible the way you tried it, can be seen in section two (Cryptokey Routing) of the paper[1].

Now onto how you can do this anyhow:
1. Multiple wireguard interfaces
	The problem being that you need more ports, because you can't listen twice on the same ip on the same port. (Well, you kind of can, but let's just say you can't).
2. Tunnel over wireguard, e.g. IPIP, GRE, VXLAN, etc
	The main drawback is that every tunneling layer comes with more overhead and it's just not a pretty solution, but it should work.

I hope this helps you in solving your problem.

Best Regards
