Multi Gateway Cloud setup

[venomone]

Hello,

i have the following scenario: 3 Hypervisors each connected with 1 Gbit to the public world and 10 Gbit interconnection for SDN and virtual machine stuff. Now i want to load balance the in/out traffic across all 3 hypervisors so that VM's can benefit from 3x 1Gbit instead of only 1 Gbit.
Now im asking myself how to realise a setup like that? In practice i need 3 OpenSense instance, one on each Hypervisor.
Do i first have to setup 3 instances of OPNsense as HA setup? Is there a good guide for this?

I'm thankful for any information and best practice advice

Every hypervisor should be connected in every WAN, then you dont have to think about this

Actually that's already the case but the port is limited to 1 Gbit on each Hypervisor to the public web which could be more
