Configuring NAT Filtering
Network Address Translation (NAT) determines how the router processes inbound traffic. 
Secured NAT provides a secured firewall to protect the computers on the LAN from attacks 
from the Internet, but might prevent some Internet games, point-to-point applications, or 
multimedia applications from functioning. Open NAT provides a much less secured firewall, 
but allows almost all Internet applications to function. For more information about NAT, see 
How Your Computer Accesses the Internet through Your Router on page 54.
To change the NAT option:
1. In the NAT Filtering area, select either the Secured or the Open radio button.
2. Click Apply to save the new configuration.
Configuring Static Routes
Static routes provide additional routing information to your router. Under usual 
circumstances, the router has adequate routing information after it has been configured for 
Internet access, and you do not need to configure additional static routes. You must configure 
static routes only for unusual cases such as multiple routers or multiple IP subnets located on 
your network.
As an example of when a static route is needed, consider the following case:
•     Your primary Internet access is through a cable modem to an ISP.
•     You have an ISDN router on your home network for connecting to the company where 
you are employed. This router’s address on your LAN is 192.168.1.100.
•     Your company’s network address is 134.177.0.0.
When you first configured your router, two implicit static routes were created. A default route 
was created with your ISP as the gateway, and a second static route was created to your 
local network for all 192.168.1.x addresses. With this configuration, if you attempt to access a 
device on the 134.177.0.0 network, your router forwards your request to the ISP. The ISP 
forwards your request to the company where you are employed, and the request is likely to 
be denied by the company’s firewall.
In this case you must define a static route, telling your router that 134.177.0.0 should be 
accessed through the ISDN router at 192.168.1.100. 
In this example:
•     The Destination IP Address and IP Subnet Mask fields specify that this static route 
applies to all 134.177.x.x addresses. 
•     The Gateway IP Address field specifies that all traffic for these addresses should be 
forwarded to the ISDN router at 192.168.1.100. 
•     A Metric value of 1 will work since the ISDN router is on the LAN. 
•     Private is selected only as a precautionary security measure in case RIP is activated.

   Chapter 4:   Customizing Your Network   Wireless-N 150 Router WNR612v2 User Manual 
To add or edit a static route:
1. 
Select  Static Routes under Advanced in the main menu. The Static Routes screen 
displays.
2.  Click  Add to expand the Static Routes screen.
3. In the Route Name field, enter a name for this static route. (This is for identification\
 
purposes only.) 
4.  Select the  Private check box if you want to limit access to the LAN only. If Private is 
selected, the static route is not reported in RIP. 
5.  Select the  Active check box to make this route effective. 
6.  In the Destination IP Address  field, enter the IP address of the final destination. 
7.  In the IP Subnet Mask  field, enter the IP subnet mask for this destination.  
If the destination is a single host, enter  255.255.255.255. 
8.  In the Gateway  IP Address field, enter the gateway IP address, which must be a router on 
the same LAN segment as the Wireless-N 150 Router WNR612v2. 
9.  In the Metric  field, enter a number between 1 and 15 as the metric value. 
This represents the number of routers between your network and the desti\
nation. Usually, 
a setting of 2 or 3 works, but if this is a direct connection, set it to\
 1. 
10.  Click  Apply to have the static route entered into the table.

Upgrading the Firmware
The wireless router’s firmware (routing software) is stored in flas\
h memory. By default, when 
you log in to your wireless router, it automatically checks the NETGEAR \
website for new 
firmware and alerts you if there is a newer version. 
Note:  To turn off the automatic firmware check at log in, clear the 
Check 
for Updated Firmware Upon Log-in check box on the Router 
Upgrade screen.
If the wireless router discovers a newer version of firmware, the messag\
e on the left displays. 
If no new firmware is available, the message on the right displays. 
To upgrade, click Yes  to allow the wireless router to download and install the new firmware.
WARNING!
When uploading firmware to the wireless router, do not interrupt 
the Web browser by closing the window, clicking a link, or loading 
a new page. If the browser is interrupted, it could corrupt the 
firmware. 
When the upload is complete, your wireless router automatically restarts\
. The upgrade 
process could take a few minutes. Read the new firmware release notes to\
 determine 
whether you must reconfigure the wireless router after upgrading.

Manually Checking for Firmware Upgrades
You can use the Router Upgrade screen to manually check the NETGEAR webs\
ite for newer 
versions of firmware for your product.
Note:  You can also check for upgrades from the NETGEAR website at 
http://www.netgear.com/support
.
To manually check for new firmware and install it on your wireless route\
r:

e. 
2. Click  Browse, and locate the firmware you downloaded (the file ends in .img or .chk\
). 
3.  Click  Upload to send the firmware to the wireless router.
WARNING!
When uploading firmware to the wireless router,  do not interrupt 
the Web browser by closing the window, clicking a link, or loading 
a new page. If the browser is interrupted, it could corrupt the 
firmware. 
When the upload is complete, your wireless router automatically restarts\
. The upgrade 
process typically takes about 1 minute. Read the new firmware release no\
tes to 
determine whether you must reconfigure the wireless router after upgradi\
ng.
Backing Up, Restoring, and Erasing Your Settings
The configuration settings of the wireless router are stored in a config\
uration file. This file can 
be backed up to your computer, restored, or reverted to factory default \
settings. The following 
procedures explains how to do these tasks.

Erasing the Configuration
Sometimes you might want to restore the wireless router to the factory d\
efault settings. You 
can do this by using the erase function.
1. In the main menu, under Maintenance, select Backup Setting, and click th\
e  Erase 
button.
2.  The wireless router then reboots automatically.
