            Bug ID: 261711
           Summary: VXLAN over wireguqard
           Product: Base System
           Version: 13.0-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: misc
          Assignee: bugs@FreeBSD.org
          Reporter: worker@cksn.tk

i am using Opnsense (freeBSD 13.0 stable) and i am trying to span a VXLAN over
a wireguard (kernel-mod and/or go implementation) tunnel. wireguard as well as
VXLAN can establish a connection but no data can be sent over the VXLAN tunnel.
the first analysis shows that the first ARP request from the remote VXLAN
interface is not answered. 
if i use for example a tinc tunnel instead of the wireguard tunnel or span the
VXLAN directly from interface to interface everything works as expected.
can anyone confirm this problem? is it possibly an opnsense specific problem?
in a clean ubuntu 20.04 the desired setup works without problems.

thank you very much and best regards,
