I hope I'm missing something really simple, but how do you configure both the WAN 1 and WAN 2 ports to be static?  In this case, I configured much of the unit via DHCP into the Internet port.  I then changed port 4 to be WAN, with a static IP (with Internet port still DHCP).  At that point, I connected the ISP modem to port 4 and connected Internet port to a non-DHCP ISP modem).  After that, I checked the device's status and saw the WAN was that of port 4.  I can't find any way to configure WAN 1 (Internet port) with the correct static IP info.  If I disconnect port 4 and reconnect WAN 1 to DCHP, the unit gets back on the Internet, but it won't let me change the WAN info to static.  I just get a yellow "!" and it never accepts the change. 
 
Any assistance would be greatly appreciated, as I'm on a tight timeline for testing and, hopefully, deployment.
 
Thank you,
