Hey guys.. for active passive HA.. do you preconfigure the passive UTM with the same interface\IP as the active info before enabling HA and plugging up eth3?
You can indeed, from the notifications page distable the notifications for HA, and it will show unlinked on the status page but you could live with that.
Really for installations with HA and one ISP put a little switch and run one to each external interface, its kind of the point of HA [:)]
