I've had U-Verse for over two years now. Since day one, I've had my Netgear router in the DMZplus mode. My router has always had a LAN static IP of 192.168.2.1. The Internet IP address is set to dynamic. Today I noticed that I could no longer connect to my NAS away from home. When I got home, I checked out my settings and noticed that the router was no longer in the DMZplus mode. Now, when I attempt to set the mode, I get this erreor:
"The selected device has a static IP address. DMZplus requires that the selected device use DHCP to obtain its IP address."
Has there been a software update lately that causes? I really want my router to keep it's 2.1 subnet. Actually, I don't know a way to allow a dynamic LAN IP address on this model (WNDR3700). Any suggestions?
EDIT: I did find a way to get my NAS working remotely and that was to add the required ports to the Allow individual application(s) option on the Uverse gateway. Guess this may be better than the DMZplus mode but still curious why all of a suddent that option no longer works.

Be sure the router is turned off when you reset to factory. I had my 3600HGV gateway still have the router behind it allocated as static after a factory reset until I did this.
After the reset, I connected my router, went to the Settings/Lan/IP Address Allocation screen, and under my router, I turned off the Firewall, selected Public address assignment, and left WAN IP Mapping (only setting). This had the effect of putting the router into the DMZplus mode when I checked the Firewall settings.
