From cd2f9bdbb7f9b737e5d640aafeb78bcd8e3a7adf Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Tue, 4 Sep 2012 05:24:47 +0200 Subject: iptables: support for target aliases This patch allows for target names listed on the command line to be rewritten to new names and revisions. As before, we will pick a revision that is supported by the kernel - now including real_name in the search. This gives us the possibility to test for many action names.
