Describe the problem

When trying to use the Networks feature, I'm unable to connect to peers over P2P if the peer's IP address is part of a larger subnet that's added as a Networks resource, where that peer is also a Routing Peer.

For example, if a peer's IP public address is 198.51.103.2.
If I add 198.51.100.0/23 as a Networks resource with that peer as one of the Routing Peers, the connection will be relayed.
If I don't use Networks and try with the peer as an exit node instead, it connects over P2P.

To Reproduce

Steps to reproduce the behaviour:

Add a peer that has an IP that's part of a larger block
Add that larger block as a Networks resource with that peer as a Routing Peer
Connect, and the connection will be relayed instead of P2P
Remove that Networks resource and it will then connect over P2P just fine

Expected behaviour

I figured it should still be able to connect directly to peers even if their IP addresses are part of a larger subnet added as a Networks resource, similar to when the peer is an exit node as that would also cover its own subnet/IP with the 0.0.0.0/0 route.

Are you using NetBird Cloud?

No, self-hosted

NetBird version

v0.45.3

Is any other VPN software installed?

No
