Allowed IPs is like a routing table; you can't have two routes for the same set of IPs, or WireGuard doesn't know which peer to send the traffic to. You want to have non-overlapping Allowed IP ranges. This usually means that the range of Allowed IPs is smaller than the host's subnet. For example: Host A: IP configuration for WireGuard interface: 192.168.123.1/24 Allowed IPs for Host B: 192.168.123.2/32 Host B: IP configuration for WireGuard interface: 192.168.123.2/24 Allowed IPs for Host A: 192.168.123.1/32 The IP configuration tells the kernel which IP ranges are accessible via the WireGuard interface. The Allowed IPs tell WireGuard, which _subset_ of those IPs is associated with each peer. > Cheers, > Gianluca Cheers, Samuel _______________________________________________ WireGuard mailing list WireGuard@lists.zx2c4.com https://lists.zx2c4.com/mailman/listinfo/wireguard
