Note:
If you are using the WNDR3400v3 base station with a
non-NETGEAR router as the repeater, you might need to change
more configuration settings. In particular, you should disable the
DHCP server function on the wireless repeater AP.
To configure the router as a repeater unit:
1.
Log in to the router that will be the repeater. Select Basic > Wireless Settings and
verify that the wireless settings match the base unit exactly. The wireless security option
has to be set to WEP or None.
2.
Select Advanced > Wireless Repeating Function, and select the Enable Wireless
Repeating Function check box for the frequency you want and the Wireless Repeater
radio button.
3.
Fill in the Repeater IP Address field. This IP address has to be in the same subnet as the
base station, but different from the LAN IP of the base station.
4.
Click Apply to save your changes.
5.
Verify connectivity across the LANs.
A computer on any wireless or wired LAN segment of the router connects to the Internet
or share files and printers with any other wireless or wired computer or server connected
to the other access point.

Port Forwarding and Port Triggering

By default, the router blocks inbound traffic from the Internet to your computers except replies
to your outbound traffic. You might need to create exceptions to this rule for these purposes:
To allow remote computers on the Internet to access a server on your local network.
To allow certain applications and games to work correctly when their replies are not
recognized by your router.
Your router provides two features for creating these exceptions: port forwarding and port
triggering. The next sections provide background information to help you understand how
port forwarding and port triggering work, and the differences between the two.

Remote Computer Access Basics

When a computer on your network needs to access a computer on the Internet, your
computer sends your router a message containing the source and destination address and
process information. Before forwarding your message to the remote computer, your router
has to modify the source information and create and track the communication session so that
replies can be routed back to your computer.
Here is an example of normal outbound traffic and the resulting inbound responses:
