The 6100 is a modem/router combination unit, meaning it contains a DSL
modem and a general purpose NAT (Network Address Translation) router.
"Bridging" means disabling both the public and private side of the NAT
router, thereby turning the 6100 into a simple DSL-to-Ethernet bridge,
or "dumb modem".
If you are already using a router, or want to, (examples: if you
already have your LAN set up and simply need to connect it to the
internet; or you want to add wireless connectivity to your connection;
or you want to use an optimised-for-gaming router; or you want to add a
VoIP router), you will want to bridge the 6100.
For optimum performance and reliability the connection should only be
going through one NAT router. When the connection goes through multiple
NAT routers, troubles like NAT conflicts will cause router lock ups and
loss of connectivity, and configuring access for things like game
consoles, VPN tunnels, remote access, server applications, security
cameras, or high-end multiplayer games will be difficult if not
Virtually all Westells with a GUI used the white & blue
"Westell" branded firmware until sometime in 2007. I believe version
4 was the last white & blue firmware. The red
"Verizon" branded firmware was rolled out in 2007. You may be running
version 5 or 6.
When the Westell is bridged, it will have no router functions at all,
no subnet, no IP, and no default gateway. The router connected to the
Westell will acquire and hold the Public IP address and will determine
the LAN IP addresses and subnet.
The Westell 6100 modem/router supplied by Verizon can be used in either
Router or Bridge mode. If you are already using a router, or want to,
you need to put the modem in Bridge mode or you'll have problems. These
instructions apply to the Westell 2200, 6100, 6100F, 327W, and 7500
• You should follow these instructions with one
PC connected to the Westell using the supplied Ethernet cable (CAT5 or
CAT5e) and that you are online and able to browse to various web sites.
If you already had a LAN setup and were online but needed to
your modem, temporarily connect one PC directly to the Westell using
the supplied Ethernet cable before continuing.
If your Westell uses the white and blue Westell
• Temporarily turn off all firewalls and pop-up blockers on the PC.
• In your browser's address box, type 192.168.1.1 to access the Modem
Configuration utility. When asked for user name and password, enter
your router's username and password (the default for the Verizon issued
routers is typically "user=admin, password=password").
• Here you may get a screen titled User Settings, this is asking you to
change the username and password for the Westell, invent and enter a
username and a password, (record these somewhere so you don't forget
• Now, from the Configuration menu, choose VC
configuration, hit the top Edit button. In the popup, set protocol to
If your Westell uses the red and black Verizon
• Then below in VC 1 Bridge Settings set the mode to Bridge.Early 6100
• Hit Set VC. Save.
• Then, again in the Configuration menu, select DHCP Configuration and
set the dropdown to OFF. Hit save and log off the utility.
• Most people don't need any more complex procedures, so try these
first. However, on occasion, you will need some additional steps,
including cloning MAC addresses. If you have trouble, check out the
diagrams and instructions here:
(Wireless Settings won't be there on the 6100 or
6100F, the left panel may be called "My Modem")
• Select the My Network icon, then select Network Connections from the
(Only the top two connections will be listed in the
6100 and 6100F)
• On the Broadband Connection screen click on the words "(Broadband
• PPPoE customers will see this screen. If you use a DHCP type Internet
connection the screen will be different, you will have a "release"
button in the top section - use it now to release your public IP. Then,
locate the VCs section, locate the line " Enabled, VPI 0, and VCI 35
..." and click the notepad icon under Edit on the right to get to the
VC 1 Configuration screen.
• In the VC 1 Configuration screen open the drop down box beside
"Protocol" and choose "Bridge". If your connection type is DHCP the
Protocol should already be "Bridge". Once Bridge is chosen, the screen
will change – open the drop down box beside "Bridge Mode" and choose
"Bridge", then click the Apply button at the bottom. This has disabled
the Public side of the 6100's router.
• The modem will reset. Next you need to disable the Private side, the
DHCP server - click the My Network icon again, click Network
Connections from the left menu again. On the Broadband Connection
screen, click the word "Lan", on the next screen remove the topmost
checkmark (Private LAN DHCP Server enable), click apply or save
• The same page will return. The Westell is now bridged, the Internet
light will no longer light, log off the utility.
Back to common steps:
• Power down and disconnect the PC from the
• Connect the Ethernet cable from the Westell to the port on your
router labeled WAN, (or Internet). Connect an Ethernet cable from one
of the LAN ports of your router to your PC. Power up the Westell, wait
for the DSL light to stop blinking then power up your router, then the
PC. When the PC boots up your firewalls and pop-up blockers may be
re-enabled, it may be necessary to turn them off again.
• Skip this next step if you've already been using your router to
supply PPPoE with your username and password.
• If your router came with a setup disk insert it now, otherwise open a
web browser and access the Router's GUI, usually at 192.168.0.1, or
192.168.1.1, or 192.168.2.1. If the router has a Setup Wizard use it,
otherwise manually configure the router for your Internet connection
type. (Note: most routers default to "Automatic" which is DHCP). If you
connect via PPPoE you will need to supply your Verizon Username and
Password so the router can acquire a Public IP address, if you connect
via DHCP you may also need to use the router's MAC cloning feature,
enter the MAC address from the Westell's label and your router will use
it to acquire a Public IP address.
• Test that you can browse to some safe web pages, then turn your
firewalls and pop-up blockers back on.
For a Westell E90-610015-06, try the instructions
in this post:
For convenience sake, here are its contents:
E90-610015-06 Verizon and Linksys wrt54g- success!
Apparently, the E90-610015-06 is for Verizon only and is slightly
different than the FAQ and Verzion support. I spent a long time on tech
support. But I could not replicate their solution. I got the westell
modem and linksys to be visible and the Linksys does the DHCP.
This is what I did. YMMV
1. Hardware reset of Linksys and Westell
2. Plug directly into Westell modem
3. Run Verizon CD to install modem and go onto network
4. Log onto Westell with new name and password
5. Go to advanced.->private Lan-> uncheck box “Private
LAN DHCP Enable”
6. My Network: copy down MAC address 01:23:23:45:ee:ab (may use later)
7. After check network connection. Turn off.
1. Plug Ethernet directly into Linksys.
2. Turn on Linksys.
3. Setup->MAC address clone-> enter in Westell number
(this step MAY not be necessary)
4. Basic setup
Internet connection type: Static
Internet IP address: 192.168.1.3
Local IP Address: 192.168.2.1
Subnet mask: 255.255.255.0
DHCP server “Enable”
Now power down. Plug an ethernet cable between the Linksys "wan" or
internet port and the Westell modem.
Power up. (westell first, Linksys second, computer third).
Check it out. Log onto 192.168.1.1. 192.168.2.1 and the web.
