Questions about HA Misconfigurations

[R1mSG]

Hi,

i have two questions regarding HA setup configurations.

1) I have two Carp IPs on one interface /29.
So far no problem, the "problem" is, one IP is /30, the other one is /29.
Can this cause problems with a HA setup?

2.) Question two, why the question 1. only arises, pfsense has a nice "Troubleshooting High Availability" page with  "Common Misconfigurations".
Do these misconfigurations all apply to OPNsense as well?

The OPNsense wiki does not have such a list, I could not identify the question from 1.) as a problem, if it is a problem at all.
