Hi,

We were installing a gateway/firewall box (running OBSD 3.1 snapshot taken
on March 12th) that needed to do nat for an internal network and binat for a
server on a dmz.

The nat rules worked fine, and we configured the permanent arp entries for
the two addresses that it was using (one for the binat, and one for nat).
However, the box never sent the arp replies when they were requested.

Finally, we had to install 3.0-stable and everything worked as it should.

Is there (or was there) a bug in the arp/proxy arp code or is there some new
syntax that is now needed for this to work in 3.1??

The command used was:

arp -s <IP> <EXTERNAL FW MAC ADDRESS> permanent pub

The arp entry was registered in the arp table, but it did not answer the
requests.

Regards,
Luis C.
