To extend your network
This topic covers cases three and four above.
NOTE
This is a complex process, so this procedure assumes that you have
some networking knowledge°
To extend your network or add wireless capabilities:
1.
If you want to extend your network, you may also follow the instructions
above° 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°
- OR -
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 32)°
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
For
ALL
Why would I 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 better way of “exposing” devices to the Internet would be to use port
forwarding° See “How to set up port forwarding” on page 53°
To set up a device in the DMZ:
Applications & Gaming > 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 server on your router” on
page 26)°
2.
Log into the browser-based utility (see “How to open the browser-based
utility” on page 22)°
3.
Click the
Applications & Gaming
tab, then click the
DMZ
page°
4.
Select
Enabled
°
5.
In the
Source IP Address
section, select
Any IP Address
to allow access
to your DMZ device from the entire Internet, or select the
source range
button and enter a range of allowed source addresses°
6.
In the
Destination
section, enter the last three digits of the IP address of
the device that will be in the DMZ° The rest of the IP address is already
completed°
