From e9c284ec4b41c827f4369973d2792992849e4fa5 Mon Sep 17 00:00:00 2001 From: Michael Braun Date: Wed, 6 May 2020 11:46:25 +0200 Subject: [PATCH] netfilter: nft_reject_bridge: enable reject with bridge vlan Currently, using the bridge reject target with tagged packets results in untagged packets being sent back. Fix this by mirroring the vlan id as well.
