What's the best way to get the caller id back? I was reading about this option. Do I need another router?
2. Secondary DMZ Similar to #1, with secondary router as a DMZ address in the Actiontec. User router must be configured for a different subnet than the Actiontec. The WAN port on the user router must also be set to use either a static IP address on the Actiontec subnet, or obtain its WAN address via DHCP. PRO: Simple config change to create DMZ address for secondary (user) router. Eliminates need to configure port forwarding in both routers. Port Forwards are configured in secondary (user) router only. No cabling changes. Can be used with either a coax or cat5 connection to the ONT. All current STB functionality supported. Guide, VOD, widgets, Remote DVR, On Screen Caller ID. CON: Secondary (user) router is double NAT'ed. Still subject to small NAT table in the Actiontec.
