I couldn't reproduce it on 23.05.1
It pulled the MAC address from my MacOS interface connected to the firewall.

Seems to be a regression on 23.09

- Status changed from New to Confirmed
Ok. I replicated the issue on:
23.09-DEVELOPMENT (amd64) built on Sat Aug 26 04:50:14 UTC 2023 FreeBSD 14.0-ALPHA2
I am changing the status to confirmed.

- Category changed from DHCP (IPv4) to Operating System
The problem here is that the behavior of the arp
command has changed. Running arp -n <ip addr>
used to limit the output to only the row for that IP address. Now it's returning all of them as if it was run with -a
. Because it's returning all of the entries, the firewall itself is first, which is where it gets that MAC address from.
Looks like a bug in arp
on FreeBSD to me. We could work around it, but given how broken the current behavior is, it would be better to get it fixed upstream.

I have conducted a test on the most recent build today and can verify that it is performing as expected.
I am marking this ticket closed.

For good measure I also tested out the arp
fixes and everything is working properly as far as I can see now.
Manually at the CLI I can filter by address and by interface.
The 'Copy My MAC' button on DHCP static mappings also works as expected from a directly connected client.
