https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290768 --- Comment #5 from relvy <it@vineyard-sha.de> --- I run three instances of tcpdump on wg1, one capturing any tcp, one capturing any udp and one capturing any icmp traffic. 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 catched 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. -- You are receiving this mail because: You are the assignee for the bug.
