From 05752523e56502cd9975aec0a2ded465d51a71f3 Mon Sep 17 00:00:00 2001 From: Jarno Rajahalme Date: Thu, 10 Mar 2016 10:54:23 -0800 Subject: openvswitch: Interface with NAT. Extend OVS conntrack interface to cover NAT. New nested OVS_CT_ATTR_NAT attribute may be used to include NAT with a CT action. A bare OVS_CT_ATTR_NAT only mangles existing and expected connections. If OVS_NAT_ATTR_SRC or OVS_NAT_ATTR_DST is included within the nested attributes, new (non-committed/non-confirmed) connections are mangled according to the rest of the nested attributes. The corresponding OVS userspace patch series includes test cases (in tests/system-traffic.at) that also serve as example uses. This work extends on a branch by Thomas Graf at https://github.com/tgraf/ovs/tree/nat.
