From 11965180ba6f278fea81f55a3aa48c8f7c667142 Mon Sep 17 00:00:00 2001 From: Mart Frauenlob Date: Wed, 10 Apr 2013 06:47:07 +0000 Subject: extensions: libxt_DNAT: rename IPv4 manpage and tell about IPv6 support This patch renames libipt_DNAT.man to libxt_DNAT.man thus informing about the IPv6 version, as suggested by Patrick McHardy. Also, it updates the list of valid protocols for port mapping is updated to: tcp, udp, dccp and sctp.
