https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D261711 Alfa <burak.sn@outlook.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |burak.sn@outlook.com --- Comment #8 from Alfa <burak.sn@outlook.com> --- Hi, I had same issue, vxlan traffic not passed thruogh wireguard kmod on FreeBSD 12.2 and 13.0 STABLE I have found that the FreeBSD's wireguard kernel implementation is the prob= lem itself. I removed Kernel implementation and installed go user space implementation it worked on FreeBSD 12.2 STABLE bot tried for 13.0. Now i tried vxlan over wg on FreebSD 14 CURRENT 20220923 AMD64 build this t= ime both wireguard kmod & go implementation didn't work. Configuration: wireguard freebsd 14 machine wg0 interface ip :192.168.199.1/24 wireguard linux machine wg0 iface ip : 192.168.199.250/24 wireguard peers connected each other successfully and available to ping one= by one but when i added vxlan like this : ifconfig vxlan700 create vxlanid 700 vxlanlocal 192.168.199.1 vxlanremote 192.168.199.250 ifconfig vxlan700 192.168.88.1/24 and i configured linux machine to meet this vxlan700 there was no traffic enters vxlan700 on bsd side The traffic doesn't pass f= rom wireguard to vxlan=20 when i listened wg interface "udp port vxlan unreachable" error occurs here is FreeBSD side logs: peer: >secret< endpoint: >secret<:10626 allowed ips: 192.168.199.250/32 latest handshake: Now transfer: 145.32 KiB received, 181.92 KiB sent persistent keepalive: every 25 seconds root@freebsd14:~ # tcpdump -i vxlan700 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on vxlan700, link-type EN10MB (Ethernet), capture size 262144 byt= es >>> there is no traffic root@freebsd14:~ # tcpdump -i wg0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on wg0, link-type NULL (BSD loopback), capture size 262144 bytes 17:21:11.801802 IP 192.168.199.250.47705 > 192.168.199.1.vxlan: VXLAN, flags [I] (0x08), vni 700 ARP, Request who-has 192.168.88.1 tell 192.168.88.2, length 46 17:21:11.801832 IP 192.168.199.1 > 192.168.199.250: ICMP 192.168.199.1 udp = port vxlan unreachable, length 104 17:21:12.825053 IP 192.168.199.250.47705 > 192.168.199.1.vxlan: VXLAN, flags [I] (0x08), vni 700 ARP, Request who-has 192.168.88.1 tell 192.168.88.2, length 46 There was same problem for freebsd 12.2 and 13 stable versions wg kmod implementations i have created a topic shown below . I was solved installin= g go implementation but this not worked for freebsd 14 . https://forums.freebsd.org/threads/vxlan-works-only-on-freebsd-11-2-but-not= -works-on-12-2-and-13-stable.81833/#post-566850 i used latest freebsd 14 current image https://download.freebsd.org/snapshots/amd64/amd64/ISO-IMAGES/14.0/FreeBSD-= 14.0-CURRENT-amd64-20220923-00d8a28f19b-258155-memstick.img.xz --=20 You are receiving this mail because: You are on the CC list for the bug.=
