VXLAN

[jens]

i also understand it like you want to use vxlan0 to connect each other,
surprisingly we are playing with this actually also - but run in
difficulties with v6 and vxlan

doing somethings like on each endpoint (both have wg0 , and this is
working fine with v6 wg internal adresses)

|ip link add vxlan0 type vxlan id 42 local <local_wg_v6>dstport 4789
nolearning bridge fdb add to <remote_mac>dst <remote_wg_v6> dev vxlan0
so fyi: (german only)

you may consider gretap tunnel - which already is working,
but i am also interested in workling vxlan setups
