Help needed: LAGG to homogenize interfaces

[cyberganny]

Hi all,

I have the challenge, that I want to build a HA Cluster of two OPNSense Firewalls that are similar but not equal. On one system is the naming schema of the interface emX on the other igbX. To make pfsync work I need two systems with equal interface names. In the doumentation is a hint to workaround via using LAGG on the interfaces:

"When using different network drivers on both machines, like running a HA setup with one physical machine as master and a virtual machine as slave, states can not be synced as interface names differ. The only workaround would be to set up a LAGG."

Now my concrete questions: How do I setup the Interfaces that it will work.

Which type of LAGG do I have to choose, due to the fact that I do not want any LAG features I only want homogenous interface names on both machines. Chosing "none" seems not be an option, because the interface will not deliver any traffic.

Which mode shall I use?

• NONE
  LACP
  FAILOVER
  FEC
  LOADBALANCE
  ROUNDROBIN

And how to configure it, if addtional settings are necessary?

Thanks in advance for help
