Seeing issue with 23.7.5-amd64 update

[Ted]

Greetings,

I updated from: OPNsense 23.7.3-amd64; FreeBSD 13.2-RELEASE-p2; OpenSSL 1.1.1v 1 Aug 2023.
to: OPNsense 23.7.5-amd64; FreeBSD 13.2-RELEASE-p3; OpenSSL 1.1.1w 11 Sep 2023

I have a /29 static subnet. The last usable address is assigned to a cable modem; the first usable address is assigned to OPNsense. It appears that I can no longer send or receive data on any of the other usable addresses in the subnet. Is there a change in the update, or required by the update, that might cause this to happen?

I'm on my way in to the facility to change out the main OPNsense for the backup OPNsense appliance.

Thanks,
Ted Dawson
