Thomas made some progress and had a working prototype, but there were some corner cases. Jarno has started thinking about NAT support for OVS and has looked at Thomas's code. I don't want to commit to any timelines, but it's something that we're going to need for OVN before too long, so I'd expect to see some progress on it. --Justin _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
