Somebody posted something similar within the past couple months, iirc.
I don't believe any answer was given. Can't say that I've seen it
myself. I believe the other person that reported this was using DHCP
on the WAN, which makes this at least a little more feasible.
Have you been able to sniff the network to see what's going on? If
you can tcpdump to a file while it's doing this and email me the data,
maybe I can see something in the output.
Technically this shouldn't be feasible. Even if m0n0wall requested an
IP from DHCP a billion times, the DHCP server should only give it one
since it should always be requested from the same MAC address.
