From d534883a52925f39c2579e8da45fab7ca57ad84b Mon Sep 17 00:00:00 2001 From: Steven Barth Date: Tue, 5 May 2015 13:22:41 +0000 Subject: [PATCH] firewall: Allow IGMP and MLD input on WAN MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The WAN port should at least respond to IGMP and MLD queries as otherwise a snooping bridge/switch might drop traffic. RFC4890 recommends to leave IGMP and MLD unfiltered as they are always link-scoped anyways.
