HA Active/passive Heartbeat sync issues.

Hi RegencyBlue 

You need to have the same Hardware model for the HA cluster to build. Refer to this link https://utm.trysophos.com/help/en_US/Content/master/managmt/High_Availability-Hardware_and_Software_Requirements.htm 

Thank you Jaydeep :)

Here's the instruction list I provide for my customers:

1. If needed, do a quick, temporary install so that the new device can download Up2Dates.
2. Apply the Up2Dates to the same version as the current unit, do a factory reset and shutdown.
3. On the current UTM in use, on the 'Configuration' tab of 'High Availability':
   a. Enable Hot-Standby
   b. Select eth3 as the Sync NIC
   c. Configure it as Node_1
   d. Enter an encryption key (I've never found a need to remember it)
   e. Select 'Enable automatic configuration of new devices'
   f. I prefer to use 'Preferred Master: None' and 'Backup interface: Internal'
4. Cable eth3 to eth3 on the new device.
5. Cable all of the other NICs exactly as they are on the original UTM.
6. Power up the new device and wait for the good news. [;)]

Thank you as always, Bob. Will bear it in mind for when we get identical hardware to our upgraded FW :)
