Subject: Wireguard, allowed-ips, ipv6 and multicast
Date: Tue, 19 May 2020 11:09:24 +0200	[thread overview]
Message-ID: <CADdae-gBznYaqgYwv9JPeGhMm86s4EZLABc-hKkTdMgUVpL-gA@mail.gmail.com> (raw)

Hello,
I'm trying to use vxlan encapsulated into Wireguard tunnel, with a
multicast group for announcement.
Ex :
ip -6 link add vxlan100 type vxlan id 100 dstport 4789  local
`wg0Ip6_lock`  group ff05::100 dev wg0 ttl 5

All works very well when i set wg tunnel with ::/0  as allowed-ips,
but if i'm trying to be more restrictive, as ff05::/32  for example,
it does not work.
Is a specific interaction between allowed-ips and multicast group in ipv6 ?

Regards,
Nicolas Prochazka.
