It has the latest firmware (it is brand new).
I heard that the ZyWall 5 was plagued with reboot problems in several places
on the Internet, so I stay away from that model.
I was hoping that someone could provide a working BIN file from a unit that
was working properly so I could upload that and just change the IPs to mine.
