Then I initiated the wireguard handshake from my peer. The result of all three tcpdump instances: 0 packets captured 0 packets received by filter 0 packets dropped by kernel If the problem were on the way out of if_wg(4) then tcpdump would have catc= hed any tcp, udp and/or icmp traffic. But there is no traffic within if_wg(4). Therefore, the problem must be on = the way *in* to if_wg(4). P.S. Let me know if I should run tcpdump with a specific filter. --=20 You are receiving this mail because: You are the assignee for the bug.=
