Hi!I am currently operating two Sophos UTM behind a router which is running great.
For redundancy reasons I now want to add another pair to operate in HA mode.
The issue: All UTM's use the SAME Interface MAC when switching to HA mode.
I can manually adjust the virtual MAC (Interface > Hardware) but after some times it's automatically chaning back to default.
Now I have two Sophos UTM (pairs in HA mode) with the same virtual MACs - my router & network of course doesn't like this.
I found an old article that it seems chaning the virtual MAC is no supported in HA mode.
Is there any solution / workaround available?
Hallo Patrick and welcome to the UTM Community!
Reading between the lines, I guess that you are in Cluster mode, not Hot-Standby - correct?
Are both clusters in the same subnet?

no, they are in Hot Standby (Active-Passive).
Both have one interface in the same (DMZ) Subnet - this is the conflicting subnet since both Interfaces have the same MAC.
Cheers - Patrick
Hey P4TR1CK V3LT3 ,Can you share a screenshot of the High Availability status , configuration, and under the interface & routing > Interfaces > Hardware !
Thanks & Regards,_______________________________________________________________
