Install & setup Wireguard instance on an wg interface. Add a CARP virtual IP to your ethernet interface (your outgoing interface if you have more than one). Add an outgoing NAT rule that does Source NAT from your ethernet IP address= to your CARP address. Setup a Wireguard peer. Do *not* use wg(8) to set the peers endpoint addres= s. When setup is done, initiate the connection from the peer. On the peer you should *not* see any incoming traffic. On your wg instance, see tcpdump -n -i udp and port 51820 see ifconfig debug and dmesg see wg show see pfctl -s states | grep 51820 --=20 You are receiving this mail because: You are the assignee for the bug.=
