I do have the Netgear router assigned to a static IP address on the LAN. I was wondering if assigning the DMZ to that IP address would work. Does the DMZ bypass the modem's built in router completely, accessing the internet directly via the same WAN address assigned by the ISP? Unfortunately I won't be on-site to try things for a few days. The modem/router supplied by the ISP is a Westell/Netgear 7500 with ISP tailored GUI. I can get into all of the settings but there is no DDNS section in programming.
