How to Bridge (Router behind Router) a AT&T; Uverse 3800 or 3801 Residential Gateway (RG) Modem to a Netgear Nighthawk AC1900 Smart WiFi Router (model R7000), . This example should work will just about any 3rd party router. This is a double NAT condition. You can also set the Netgear as an Access Point instead. .......................... Info: Just so you know, Bridging; which very specifically means the downstream router gets a public routable IP without double NATting the machines behind it. This setup DOES have Double NAT. This setup isn't a TRUE BRIDGE, So yeah we shouldn't call this method a Bridge, it's more like port forwarding, but since we are stuck with the Uverse Gateway (DVR Set Top Box cable has to be connected to the Uverse RG) this is the closest we are gonna get and works fine. Unless your are going to have a NAS setup with remote connections (server), then you may want to set the 3rd party router as an Access Point. Note: The Uverse RG has a section under Broadband; Link Configuration and under Supplemental Network makes it sound like you can Bridge the RG, but you would loose the ability of the DVR Set Top Box (DVR STB) and be totally useless. So don't use that function. The DVR STB has to be plugged into the RG! ................................. You can manually Bridge the RG but this video shows you how to use the RG's built in "Router behind Router" method. I think this method helps setting things up properly, as who knows what AT&T; MAY do behind the scenes that we don't know about. AT&T; Uverse (RG) modems only use 802.11 b/g 54Mbps 802.11 wireless, they don't have gigabit networking ports, have limited features, and are just poor routers. Adding a 3rd party router will open up a whole new world of options. I suggest to use Cat 6 networking cables throughout your network. The 2Wire 3801 now only acts as a modem. The 3rd party router now has full control and now I have great WiFi, port forward, and a host of other features with the Netgear AC1900 / R7000. If you want to know how to set up manually, here is the Basic method of setting it up: 1. Set your router's WAN interface to get an IP address via DHCP. This is required at first so that the ATT RG router recognizes your 3rd party router. 2. Plug your router's WAN interface to one of the ATT RG's LAN interfaces. 3. Restart your router; let it get an IP address via DHCP. 4. Log into the ATT router's interface. Go to Settings; Firewall ; Applications, Pinholes, and DMZ 5. Select your router under section 1. 6. Click the DMZPlus button under section 2. 7. Click the Save button. 8. Restart your router, when it gets an address via DHCP again, it will be the public outside IP address. At this point, you can leave your router in DHCP mode, or you can change your router's IP address assignment on the WAN interface to static, and use the same settings it received via DHCP. 9. On the ATT router, go to Settings; Firewall; Advanced Configuration 10. Uncheck the following: Stealth Mode, Block Ping, and Strict UDP Session Control. 11. Check everything under Outbound Protocol Control except NetBIOS. (default) 12. Uncheck NetBIOS under Inbound Protocol Control. (default) 13. Uncheck all the Attack Detection checkboxes; 7 of them. 14. Click Save. 15. Done *** Also, if your area allows the newer modem (NVG589) just call ATT and claim outage issues, and you heard about the newer NVG589 modem and want to exchange it. The NVG589 has upgraded hardware on-board and is N capable.
