  4. The default username for your Motorola NVG510 is blank and the default password is blank. If you’ve recently done a reset, or have not changed it yet, it should remain the default. If you’ve changed this at some point, but are not sure what it is anymore, you can always do a quick factory reset to set it back to the defaults.
  5. In the login page of the router’s web user interface, Enter the username & password, hit “Login” and now you should see the Motorola NVG510 router control panel
  6. Once you’ve logged in, head to the “Home Network” and then the “Wireless” settings tab at the top of the page. There, you’ll find all settings pertaining to the WiFi.
    • Network Name (SSID): This is the network name you’ll see in your WiFi network list. Make sure it’s something you’ll remember as your network.
    • Key: This is your WiFi password. Make sure to set it to something that’s at least 8 characters long, and is secure. It’s recommended to include at least 1 symbol, 1 uppercase, and one number in your password for the maximum security of your network.
  7. After adjusting the settings for your network, always remember to hit save before closing out of the admin panel.

How to Set Motorola NVG510 to Bridge Mode

The easiest way to upgrade your home network while using the Motorola router NVG510 is to set it to bridge mode, and then use your own, separate router to handle the WiFi part of your service. This allows you to upgrade your WiFi speed and range, and often permits you to add some more enhanced features, such as Dual-Band, or mesh network systems to your network. Here’s our manual on setting your Motorola router NVG510 to bridge mode in order to forward your wireless to your new router.

Important Note: If you use AT&T uVerse Voice (VoIP) service it is not recommended to put your Motorola NVG510 Gateway into IP Passthrough mode. IP Passthrough mode causes issues with uVerse Voice service and causes incoming calls to not connect properly, and instead gives an error message. If you use AT&T uVerse Voice Service you are essentially required to use this device to power your home network.

Bridge mode, DMZ+, or IP Passthrough are the features that permit you to run your own router behind the AT&T provided residential gateway with a public IP address on its outside WAN interface. The NVG510 supports the IP Passthrough feature to accomplish this.

To be technically accurate, the NVG510 does not actually “bridge” the traffic. It will enable a default rule to forward all unknown inbound traffic to the AT&T public IP address to the MAC address of the internal router. This will preserve the public destination IP address on incoming packets and allow you to control inbound access for services and security from your personal router.

 

The NVG510 will still map session state information for each connection passing through, similar to a traditional NAT configuration. The only thing it will do with this traffic is rewrite the destination MAC address to that of your personal router’s WAN interface. The NVG510 includes more memory and can support 8192 simultaneous connection entries, as compared to previous gateways that were limited to a maximum of 1024.

 

Make sure you have a notebook or a computer that you can directly connect to the NVG510.  Once you have that, unplug all Ethernet cables (including television STBs) from the Motorola router NVG510 except for the previously mentioned notebook/computer. Note: the WAN connection from AT&T is not an Ethernet connection. Second, write down the WAN-side MAC Address of your personal router.

Configuration steps to perform on the NVG510:

Note: 192.168.10.1-254 address block is a suggestion in this series of steps.  Feel free to adjust this as you wish.

1. Login to the NVG510’s web-based configuration interface in your web browser.

This can usually be accessed with the following link:  https://192.168.1.254

2. Go to the “Home Network” -> “Subnets & DHCP” tab.  It may ask for your NVG510’s password.

3. If your “Device IPv4 Address” is in the same subnet as your personal router’s LAN segment, you should change your personal router’s network configuration to use a different subnet like 192.168.10.0 or whatever you wish, as long as it continues to use private address space in the 192.168.0.0/16, 10.0.0.0/8, or 172.16.0.0/12.  The subnet mask can stay the same, 255.255.255.0, or can be adjusted to a larger range if you want.

4. Leave the default DHCP settings on the NVG510 as is, unless you want to expand the usable range. This will permit your Television Set Top Boxes to connect and any other devices that you may want to use the integrated wireless or wire directly to the RG. The Television STBs can not connect to your personal router, unless your router has the capability to provide Multicast Routing using IGMPv3. Most consumer routers do not have this capability.

It is important that you have only your computer that’s configuring the NVG510 connected to it at this time.

5. If you have made any changes, at this point, Click “Save” at the bottom.

6. Go to the “Home Network” -> “Wireless” tab.

7. If you do not want to use the NVG510’s integrated wireless feature, disable Wireless by choosing “Off” in the “Wireless Operation” option.

8. Go to the “Firewall” -> “Packet Filter” tab.  Click on the “Disable Packet Filters” button.

9. Go to the “Firewall” -> “NAT/Gaming” tab and disable any and all settings.

10. Go to the “Firewall” -> “IP Passthrough” tab.  Select “Passthrough” in the “Allocation Mode” option.

11. Do not enter anything for the “Default Server Internal Address”. Leave this field blank.

12. In the “Passthrough Mode” selection choose “DHCPS-Fixed”.

13. Type in the WAN-side MAC Address for your router under “Manual Entry”, lowercase is fine. The MAC address should be in the traditional hexadecimal format xx:xx:xx:xx:xx:xx where the x’s should be values from 0-9 or letters a-f, separated with single colons. If you have already connected the WAN interface of your personal router and configured it for DHCP, it may show up in the “Choose from list”. If you select it, it will automatically fill the field with appropriate MAC address.

14. The Passthrough DHCP Lease value defaults to 10 minutes. You can not change this.

15. Click “Save” at the bottom. It will tell you that it needs to reboot. Stop! Do not reboot the router, yet.

16. If you are not putting any devices on the network segment directly attached to the AT&T gateway and do not want any of the Firewall security features active on the NVG589, go to the “Firewall Advanced” tab at the top and turn everything off. The recommendation is to leave these features enabled if you will have any devices on this segment or are using the integrated wireless feature. If you disable these features, make sure you are enabling this functionality on your personal router.

17. Near the top of your screen, you should see an option telling you to reboot the router. Go ahead and do this now. It takes about 2 minutes.

Configuration steps for your personal router:

1. Disconnect your laptop’s ethernet connection from the NVG510 and connect your personal router, while the modem reboots.

2. Connect your laptop to your personal router.

3. Login to your personal router and change the Internet connection type to DHCP as per your router’s instructions.

You should be done configuring the IP Passthrough “bridge mode”, at this point. Make sure to verify that your personal router is being assigned the public IP address from AT&T on its WAN interface via DHCP.
