1) Download the ItusgatewayImage file and transfer it to the Shield
1a) For Original Itus Firmware users:
   mount /dev/mmcblk0p1 /overlay
   ssh -q -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null ItusgatewayImage root@10.10.10.10:/overlay
   umount /overlay
   Ensure the front-switch is set to the Outer (Gateway) mode and reboot -f
1b) For users who are already on my firmware:
   mount /dev/mmcblk1p1 /overlay
   ssh -q -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null ItusgatewayImage root@10.10.10.10:/overlay
   umount /overlay
   rm /.norwits
   Ensure the front-switch is set to the Outer (Gateway) mode and reboot

(The front switch is only read at boot time, so you can switch it as much as you want after it boots without issue - It only tells the bootloader which image files to pick)

I have ID'ed a small bug in which the system seems to be stuck in that Gateway mode I mentioned.  This SHOULD be a configuration issue, so you can still feel free to play and test.

Right now, the Shield is forwarding DHCP requests out through the WAN rather than servicing them itself (https://forum.openwrt.org/t/dhcp-relaying-instead-of-serving/62583/4)

The negative side is that you CANNOT get to luCi/ssh at the moment..  I'm working on it, but everything can still be done via console.  If this is daunting, I'd wait to upgrade until I get more settled out.  Keep in mind, this does not alter any of the other images (bridge or router) on the device, so you can always just switch back and forth.
