Little Confused

[viper359]

I am looking to do a HA setup
Master will be a Proxmox VM
Secondary will be a physical Sophos XG450 appliance

Do I understand right, because the interfaces on each machine will probably be named different,
high availability wont work?

You can create a lagg interface with a single member from each physical or virtual port forcing the names to be identical.

Or just rename them on Proxmox (rename the virtual NIC attached to the VM).

But your understanding is correct. In order to sync properly it has to have same naming conventions.

You can force the interface name by using device hints.

Edit device.hints from the shell and edit (or create) the file /boot/device.hints
Add entries to bind the MAC address to a specific device name.
Example: To make a specific Intel card (igb0) always be lan0:
hint.igb.0.mac="00:11:22:33:44:55"
hint.igb.0.name="lan0"

This will keep the interface names identical between your boxes.

Code Select Expand

hint.igb.0.mac="00:11:22:33:44:55"
hint.igb.0.name="lan0"


Wow! TIL. Thanks!

I know the answer, but.... Why This is not a thing directly in the GUI? :)
