That reply could not have been more consise and clear! Makes sense. Thanks a lot rseibert!
Does it matter that my configs are not in sync? Its a matter of 2-3 commands that actually dont make sense to not have been synced ( router id on one of my virtual routers non existing on the backup, an interface being in a zone while on the other firewall being unused and a random (or so i think) static route which i fixed.) Actually i dont want to force config since i cant have the box resetting now.
