Advanced Configuration
v1.0, March 2010
In this case you must define a static route, telling your router that 134.177.0.0 should be accessed
through the ISDN router at 192.168.0.100. The static route would look like
Figure 5-6
.
In this example:
The
Destination IP Address
and
IP Subnet Mask
fields specify that this static route applies
to all 134.177.x.x addresses.
The
Gateway IP Address
fields specify that all traffic for these addresses should be
forwarded to the ISDN router at 192.168.0.100.
In the
Metric
field, a value of 1 will work since the ISDN router is on the LAN.
This represents the number of routers between your network and the destination. This is a
direct connection, so it is set to 1.
Private
is selected only as a precautionary security measure in case RIP is activated.
Configuring Static Routes
1.
Log in to the modem router at its default LAN address of
with its default
user name of
admin
and default password of
password
, or using whatever user name,
password and LAN address you have chosen for the modem router.
2.
From the main menu, under the Advanced heading, select Static Routes to view the Static
Routes screen:

Fill in or change the fields:
Route Name.
The route name is for identification purposes only.
Private
. Select this check box if you want to limit access to the LAN only.
The static route will not be reported in RIP.
Active
. Select this check box to make this route effective.
Destination IP Address
, and
IP Subnet Mask
. If the destination is a single host, type a
subnet value of
255.255.255.255
.
Gateway IP Address
. This must be a router on the same LAN segment as the modem
router.
Metric
. Type a number between 2 and 15. This represents the number of routers between
your network and the destination. Usually, a setting of 2 or 3 works, but if this is a direct
connection, set it to 2.

Click
Apply
to either save your changes. If you added a static route, it is added to the Static
Routes screen.
Configuring Universal Plug and Play (UPnP)
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.

1.
Select UPnP on the main menu to display the UPnP screen:
2.
Fill in the settings on the UPnP screen:
Turn UPnP On
. UPnP can be enabled or disabled for automatic device configuration. The
default setting for UPnP is enabled. If disabled, the modem router will not allow any
device to automatically control the resources, such as port forwarding (mapping), of the
modem router.
Advertisement Period
. The advertisement period is how often the modem router
advertises (broadcasts) its UPnP information. This value can range from 1 to 1440
minutes. The default period is for 30 minutes. Shorter durations ensure that control points
have current device status at the expense of additional network traffic. Longer durations
might compromise the freshness of the device status but can significantly reduce network
traffic.
Advertisement Time To Live
. The time to live for the advertisement is measured in hops
(steps) for each UPnP packet sent. A hop is the number of steps 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, then it might be necessary to increase this value a little.
UPnP Portmap Table
. The UPnP Portmap Table displays the IP address of each UPnP
device that is currently accessing the modem router and which ports (internal and external)
that device has opened.

Chapter 6
Virtual Private Networking
This chapter describes how to use the virtual private networking (VPN) features of the ADSL2+
Modem Wireless Router. VPN communications paths are called tunnels. VPN tunnels provide
secure, encrypted communications between your local network and a remote network or computer.
See
“Virtual Private Networking (VPN)” in Appendix C
to learn more about VPN.
This chapter is organized as follows:
“Overview of VPN Configuration” on page 6-1
provides an overview of the two most
common VPN configurations: client-to-gateway and gateway-to-gateway.
“Planning a VPN” on page 6-3
provides a worksheet for recording the configuration
parameters of the VPN you want to set up, along with the VPN Committee (VPNC)
recommended default parameters set by the VPN Wizard.
“VPN Tunnel Configuration” on page 6-4
summarizes the three ways to configure a VPN
tunnel: VPN Wizard (recommended for most situations), Auto Policy, and Manual Policy.
“Setting Up a Client-to-Gateway VPN Configuration” on page 6-5
provides the steps needed
to configure a VPN tunnel between a remote PC and a network gateway using the VPN
Wizard and the NETGEAR ProSafe VPN Client.
“Setting Up a Gateway-to-Gateway VPN Configuration” on page 6-18
provides the steps
needed to configure a VPN tunnel between two network gateways using the VPN Wizard.
“VPN Tunnel Control” on page 6-25
provides the step-by-step procedures for activating,
verifying, deactivating, and deleting a VPN tunnel once the VPN tunnel has been configured.
“Setting Up VPN Tunnels in Special Circumstances” on page 6-32
provides the steps needed
to configure VPN tunnels when there are special circumstances and the VPNC recommended
defaults of the VPN Wizard are inappropriate. The two alternatives for configuring VPN
tunnels are Auto Policy and Manual Policy.
Overview of VPN Configuration
Two common scenarios for configuring VPN tunnels are between a remote PC and a network
gateway; and between two or more network gateways. The DG834G v5 supports both of these
types of VPN configurations. The DG834G v5 supports up to five concurrent tunnels.

Client-to-Gateway VPN Tunnels
Client-to-gateway VPN tunnels provide secure access from a remote PC, such as a telecommuter
connecting to an office network.
A VPN client access allows a remote PC to connect to your network from any location on the
Internet. In this case, the remote PC is one tunnel endpoint, running the VPN client software. The
modem router on your network is the other tunnel endpoint. See
“Setting Up a Client-to-Gateway
VPN Configuration” on page 6-5
to set up this configuration.
Gateway-to-Gateway VPN Tunnels
Gateway-to-Gateway VPN Tunnels provide secure access between networks, such as a branch or
home office and a main office.
A VPN between two or more NETGEAR VPN-enabled routers is a good way to connect branch or
home offices and business partners over the Internet. VPN tunnels also enable access to network
resources across the Internet. In this case, use DG834G v5s on each end of the tunnel to form the
VPN tunnel end points. See
“Setting Up a Gateway-to-Gateway VPN Configuration” on page 6-18
for information about how to set up this configuration.
