To extend your network or add wireless capabilities (cases 3 and 4 above), do one of the following:
Note---- - This is a complex process, so this procedure assumes that you have some networking
knowledge.
1. Follow the instructions above for adding a router to share an Internet connection.
One example of this might be to provide a separate wireless network for your children to keep
their wireless network traffic separate from your wireless network. You might also want to
isolate one network from another network so that network shares aren't visible across
networks. In this case, use an Ethernet cable to connect the Internet port of the downstream
router to one of the LAN ports of the upstream router. Make sure that the local network
subnets on the two routers are different.
2. You can extend your network by turning the downstream router into an access point. (See
''How to use a router as an access point'' on page 47.) When you use a router as an access
point, computers connected to the access point are on the same IP subnet as all other devices
connected to the router. File, printer, and media sharing is much easier if all devices are on the
same subnet.

How to expose a device to the Internet

If you are operating a web server, a mail server, or a web camera, you may want to expose that device
to the Internet so anybody can access it. Your router includes a DMZ (Demilitarized Zone) feature
that forwards all inbound ports presented on the WAN interface, except those that are specifically
forwarded, to an individual IP address or MAC address. This feature is normally not used, because it
presents significant security risks to the device that you designate for the DMZ. The DMZ device is
not protected by the built-in firewalls, Internet filters, or router web filters, and is open to attacks
from hackers.
A much safer way of exposing devices to the Internet would be to use port forwarding. See ''How to
set up port forwarding'' on page 54.
To set up a device in the DMZ:
1. Configure your device with a static IP address. See your device's documentation for help with
setting a static IP address or use DHCP reservation (see ''How to set up the DHCP
reservations'' on page 40).
2. Log in to Linksys Smart Wi-Fi. (See ''How to connect to Linksys Smart Wi-Fi'' on page 10.)
