[Users] Cannot Ping CARP/Spoofed address

Hi Guys, I'm trying to use Mac spoofing for a Carp setup which is not working out well. Following here: https://forum.pfsense.org/index.php?topic=68137.0 and here http://lists.ovirt.org/pipermail/users/2013-October/017217.html This should be working by: engine-config -s EnableMACAntiSpoofingFilterRules=false --cver=3.3 (The clusters are 3.3 compatible) In some strange way this is not working in any way. How can we solve this, as I'm out of options. Thanks! Matt
