Description

This was brought up by a customer and I am able to reproduce it.

Master 10.41.1.252
Backup 10.40.1.253
CARP 10.40.1.254

10.40.1.253 is unable to ping 10.40.1.254 on 23.01, but is able to on a 22.05 install.

When pinging 10.40.1.253 > 10.40.1.254 and using packet capture it shows packets reaching 10.41.1.252 and replies making it back to 10.41.1.253, but ping never sees the response. There are no blocked entries in the firewall logs.
