N300 Wireless ADSL2+ Modem Router DGN2200v4
Normal web browser access uses the standard HTTP service port 80. For greater
security, enter a custom port number for the remote web management interface. Choose
a number from 1024 to 65535, but do not use the number of any common service port.
The default is 8080, which is a common alternate for HTTP.

When you access your modem router from the Internet, type your modem router’s WAN IP
address into your browser’s address or location field followed by a colon (:) and the custom
port number.
For example, if your external address is 134.177.0.123 and you use port number 8080,
enter
in your browser.
Universal Plug and Play
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,
access the network and connect to other devices as needed. UPnP devices can
automatically discover the services from other registered UPnP devices on the network.
If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time
communications such as instant messaging or remote assistance (a feature in Windows XP),
you should enable UPnP.
To turn on Universal Plug and Play:
1.
Select
Advanced > Advanced Setup >
UPnP
.
2.
Select the Turn UPnP On check box.
By default, this check box is selected. UPnP for automatic device configuration
can be enabled or disabled. If the Turn UPnP On check box is cleared, the
modem
router
does not allow any device to automatically control the resources, such as
port forwarding (mapping), of the
modem router
.
3.
Type the advertisement period in minutes.
The advertisement period specifies how often the
modem router
broadcasts its
UPnP information. This value can range from 1 to 1440 minutes. The default period
is 30 minutes. Shorter durations ensure that control points have current device
status at the expense of additional network traffic. Longer durations can

compromise the freshness of the device status, but can significantly reduce
network traffic.
4.
Type the advertisement time to live in hops.
The time to live for the advertisement is measured in hops (steps) for each UPnP
packet sent. The time to live hop count is the number of steps a broadcast packet is
allowed to propagate for each UPnP advertisement before it disappears. The
number of hops can range from 1 to 255. The default value for the advertisement
time to live is 4 hops, which should be fine for most home networks. If you notice
that some devices are not being updated or reached correctly, it might be
necessary to increase this value.
5.
Click the Apply button.
The UPnP Portmap Table displays the IP address of each UPnP device that is
accessing the
modem router
. The UPnP Portmap Table also shows which ports are
open, what type of ports are open, and whether each open port is still active for
each IP address.
To refresh the information in the UPnP Portmap Table, click the Refresh button
.
IPv6
You can use this feature to set up an IPv6 Internet connection type if genie does not detect it
automatically.
To set up an IPv6 Internet connection type:
1.
Select
Advanced > Advanced Setup > IPv6
.
2.
In the Internet Connection Type list, select the IPv6 connection type.
Your Internet service provider (ISP) can provide this information.
•
If your ISP did not provide details, you can select
IPv6 Tunnel
.
•
If you are not sure, select
Auto Detect
so that the modem router detects the IPv6
type that is in use.
•
If your Internet connection does not use PPPoE, DHCP, or fixed, but is IPv6, select
Auto Config
.
For more detailed information about Internet connection types, see the following sections.

Requirements for Entering IPv6 Addresses
IPv6 addresses are denoted by eight groups of hexadecimal quartets that are separated by
colons. Any four-digit group of zeroes within an IPv6 address can be reduced to a single zero
or altogether omitted.
The following errors invalidate an IPv6 address:
•
More than eight groups of hexadecimal quartets
•
More than four hexadecimal characters in a quartet
•
More than two colons in a row

Auto Detect
To set up an IPv6 Internet connection through auto detection:

.
The screen adjusts:
The modem router automatically detects the information in the following fields:
•
Connection Type
. This field indicates the connection type that is detected.
•
Router’s IPv6 Address on WAN
. This field shows the IPv6 address that is acquired
for the modem router’s WAN (or Internet) interface. The number after the slash (/) is
the length of the prefix, which is also indicated by the underline (_) under the IPv6
address. If no address is acquired, the field displays Not Available.
•
Router’s IPv6 Address on LAN
. This field shows the IPv6 address that is acquired
for the modem router’s LAN interface. The number after the slash (/) is the length of
the prefix, which is also indicated by the underline (_) under the IPv6 address. If no
address is acquired, the field displays Not Available.
3.
Specify how the modem router assigns IPv6 addresses to the devices on your home
network (the LAN) by selecting one of the following radio buttons:
•
Use DHCP Server
. This method passes more information to LAN devices, but some
IPv6 systems might not support the DHCv6 client function.
•
Auto Config
. This is the default setting.
4.
(Optional) Select the
Use This Interface ID
check box, and specify the interface ID that you
want to be used for the IPv6 address of the modem router’s LAN interface.
If you do not specify an ID here, the modem router generates one automatically from its
MAC address.

(Optional) In the DHCP User Class (If Required) field, enter a host name.
Most people do not need to fill in this field, but if your ISP has given you a specific host
name, enter it here.
4.
(Optional) In the Domain Name (If Required) field, enter a domain name.
You can type the domain name of your IPv6 ISP. (Do not enter the domain name for the
IPv4 ISP here.) For example, if your ISP’s mail server is mail.xxx.yyy.zzz, you would type
xxx.yyy.zzz as the domain name. If your ISP provided a domain name, type it in this field.
(For example, Earthlink Cable might require a host name of home, and Comcast
sometimes supplies a domain name.)
