It came out that after this change Wireguard protocol is able to do a handshake with IPv6 specified endpoint, = but sizeof(*endpoint)[1] seems to be always 16(for both legacy IP and IPv6 specified endpoints), what is fine for legacy IP, while for IPv6 endpoint s= ize is 28. After disabling this check no more than Wireguard handshake over IPv6 can be observed. The tunnel is either not created or not able to carry the data.[2] [1] https://cgit.freebsd.org/src/tree/sys/dev/if_wg/module/module.c?id=3D5aaea4= b#n590 [2] https://lists.freebsd.org/pipermail/freebsd-net/2021-February/057463.ht= ml --=20 You are receiving this mail because: You are the assignee for the bug.=
