From ad49d86e07a497e834cb06f2b151dccd75f8e148 Mon Sep 17 00:00:00 2001 From: Fernando Fernandez Mancera Date: Wed, 26 Jun 2019 12:59:19 +0200 Subject: netfilter: nf_tables: Add synproxy support Add synproxy support for nf_tables. This behaves like the iptables synproxy target but it is structured in a way that allows us to propose improvements in the future.
