Manage Heartbeat High Availability

Add a new multicast synchronization.

Set up a multicast heartbeat on an interface. Multicast heartbeat is a very useful way of managing synchronization between two HA units. Note, do not forget to setup a rule for multicast in your incoming and outgoing rulebase.

Option	New Value	Explanation
Device		Device to send/rcv heartbeats on.
Multic. IP		Multicast group to join (class D multicast address 224.0.0.0 - 239.255.255.255)
Port		Udp port to sendto/rcvfrom (no real reason to differ from the port used for broadcast heartbeats).
Ttl		The ttl value for outbound heartbeats. This effects how far the multicast packet will propagate. (0-255).
Loop		Toggles loopback for outbound multicast heartbeats. If enabled, an outbound packet will be looped back and received by the interface it was sent on. (0 or 1).
