So what happens if you now configure the DHCP server so that the (working) IP is removed from the pool, and have the DHCP server explicitly assign it to the device instead?  Does it still work?  What if you turn the DHCP client off in the ATA, and try to manually assign the ATA both the fixed IP that didn't work, and the IP that does?

There has to be a difference somewhere, whether it is in the DHCP payload, the way a router or NAT engine upstream is treating that IP, or *something*.
