Subject: [PATCH nf-next v4 0/2] nat: force port remap to prevent shadowing well-known ports
Date: Fri, 17 Dec 2021 11:29:55 +0100	[thread overview]
Message-ID: <20211217102957.2999-1-fw@strlen.de> (raw)

Hi,

This is a resend of the port remap change with auto-exception for
locally originating connections.

This is done by adding a bit in nf_conn for LOCAL_OUT tracked entries.

Patch 1/2 is same as in v2.
Patch 2/2 is same as v3.
v3 only contained patch 2/2 by mistake.
