Title: VXLAN via Wireguard
Post by: skydiablo on August 17, 2021, 09:59:21 AM
Hi,
i have set up a VXLAN tunnel over a wireguard connection. unfortunately i don't get any data over the VXLAN tunnel, according to my research it already fails at the ARP request. if i send a ping at host1 towards host2, an ARP request arrives at host2 but unfortunately it is never answered?! what could be the reason for this?

a second VXLAN tunnel that goes directly over the LAN interface runs without problems, only when I put wireguard below it I have the ARP problems.

regards, volker.

this is an accepted issue and already fixed in BSD main-line: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261711

is this already merged into the current opnsense kernel? my current tests arent working yet, so i asking.
