Port Forwarding And Port Triggering; Remote Computer Access Basics - NETGEAR MBR1515 User Manual

Note: If you are using the MBR1515 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 is to 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 > Advanced > Wireless Repeating Function. 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 address 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 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 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 do not get
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:
