From 8af8718bc2613c941e8ce4e39fce0d856cc8fd8a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Linus=20L=C3=BCssing?= Date: Sat, 22 Aug 2020 13:17:40 +0200 Subject: [PATCH] gluon-ebtables-filter-multicast: allow respondd queries MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This allows running a respondd querier and map server behind a Gluon node. For instance at Freifunk Lübeck we now moved the map server behind a Gluon VM and removed batman-adv and fastd from the map server VM to reduce the maintenance work. Increased multicast overhead should be minimal / non existent, as it is unlikely to accidentally have respondd queriers running behind a Gluon node.
