https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290768 --- Comment #7 from relvy <it@vineyard-sha.de> --- (In reply to Kyle Evans from comment #4) I tested the mentioned commit. The tcpdump output: tcpdump: verbose output suppressed, use -v[v]... for full protocol decode listening on igc0, link-type EN10MB (Ethernet), snapshot length 262144 bytes 17:55:41.268806 e0:28:6d:89:6b:02 > 00:00:5e:00:01:01, ethertype IPv4 (0x0800), length 190: a.b.c.d.60586 > 192.168.178.2.51820: UDP, length 148 17:55:41.268880 00:90:27:e6:33:13 > e0:28:6d:89:6b:02, ethertype IPv4 (0x0800), length 190: a.b.c.d.60586 > 192.168.178.2.51820: UDP, length 148 17:55:41.873931 00:90:27:e6:33:13 > e0:28:6d:89:6b:02, ethertype IPv4 (0x0800), length 190: 192.168.178.10.51820 > a.b.c.d.51820: UDP, length 148 17:55:46.336997 e0:28:6d:89:6b:02 > 00:00:5e:00:01:01, ethertype IPv4 (0x0800), length 190: a.b.c.d.60586 > 192.168.178.2.51820: UDP, length 148 17:55:46.337014 00:90:27:e6:33:13 > e0:28:6d:89:6b:02, ethertype IPv4 (0x0800), length 190: a.b.c.d.60586 > 192.168.178.2.51820: UDP, length 148 17:55:47.062936 00:90:27:e6:33:13 > e0:28:6d:89:6b:02, ethertype IPv4 (0x0800), length 190: 192.168.178.10.51820 > a.b.c.d.51820: UDP, length 148 And in dmesg I see: [78] wg1: Handshake for peer 1 did not complete after 5 seconds, retrying (try 13) [78] wg1: Sending handshake initiation to peer 1 [78] wg1: Unable to send packet: 47 So this indeed does fix the src / dst IP reversal. There are two issues left: First, the destination *port* in the reply is not correct Second, in the message "Unable to send packet: 47" the 47 means unknown address family. -- You are receiving this mail because: You are the assignee for the bug.
