UTM HA Hyper-V

AlexHarding

Hi all

I have a slight issue.

We use Hyper-v as our Hyper-visor. I have configured 1 UTM which is live and is working fine.
I have also configured another UTM to allow me to configure HA across two separate hosts.

However the issue is when I enable HA both the UTMS go offline and will not come back up. I left the UTMS for 15 minutes but they do not come back online.
The only way to get the UTM back online is to disable HA via the console.

 I have created a virtual switch and selected a dedicated NIC.
The interface type is set to external and to not Allow management operating system to share this network adapter.

I have enabled jumbo frames on the physical network adapter. There is no switch in-between the HA it is a direct link between Hyper-V Hosts.

I have set and checked the MTU packet size via the console and the HA nic is set to 2000.

I have mirrored the settings on the other Hyper-V host and UTM, but this does not  make a difference. 

I have also enabled Mac address spoofing as I believe this is required. 

When enable HA the UTM will be on for around 40 - 60 seconds and then goes offline and all network access is unable to reach the UTM.

Anyone got any ideas? :)
