Port Forwarding And Triggering; Remote Computer Access Basics - NETGEAR D6300 User Manual

Note: If you are using the D6300 base station with a non-NETGEAR WiFi
modem router as the repeater, you might need to change additional
configuration settings. In particular, you should disable the DHCP
server function on the wireless repeater AP.

To configure the WiFi modem router as a repeater unit:
1. Log in to the WiFi modem router that is 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 > Advanced Setup > Wireless Repeating Function, and select the
Enable Wireless Repeating Function check box 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 WiFi modem router should be
able to connect 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 Triggering

By default, the WiFi modem 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 WiFi modem router.
Your WiFi modem 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 WiFi modem router a message containing the source and destination
address and process information. Before forwarding your message to the remote computer,
your WiFi modem 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:
