ISATAP Tunnels Configurati on
ISATAP Subnet Prefix: This is the 64-bit subnet prefix that is assigned
to the logical ISATAP subnet for this intranet. This can be obtained from
your ISP or internet registry, or derived from RFC 4193.
End Point Address: This is the endpoint address for the tunnel that starts
with this router. The endpoint can be the LAN interface (assuming the
LAN is an IPv4 network), or a specific LAN IPv4 addres s .
IPv4 Address: The end point address if not the entire LAN.

Configurable Port - WAN Option
This router supports one of the physical ports to be configured as a secondary WAN
Ethernet port or a dedicated DMZ port. If the port is selected to be a secondary WAN
interface, all configuration pages relating to WAN2 are enabled.
3.7
WAN 3 (3G) Configuration
This router supports one of the physic al ports WAN3 to be configured for 3G internet
access.
Setup > Internet Settings > WAN3 Setup
WAN3 configuration for the 3G USB modem is available only on WAN3 interface.
There are a few key elements of WAN 3 configuration.
Reconnect Mode: Select one of the following options
o
Always On: The connection is always on. Username: Enter the username
required to log in to the ISP.

o
On Demand: The connection is automatically ended if it is idle for a
specified number of minutes. Enter the number of minutes in the
Maximum Idle Time field. This feature is useful if your ISP charges you
based on the amount of time t hat you are connected.
Password: Enter the password required to login to the ISP.
Dial Number: Enter the number to dial to the ISP.
Authentication Protocol: Select one of None, PAP or CHAP Authentication
Protocols to connect to the ISP.
APN: Enter the APN (Access Point Name) provided by the ISP.
Domain Name System (DNS) Servers
Domain name servers (DNS) convert Internet names such as www.dlink.com, to
IP addresses to route traffic to the correct resources on the Internet. If you
configure your router to get an IP address dynamically from the ISP, then you
need to specify the DNS server source in this section.
DNS Server Source: Choose one of the following options:
o
Get Dynamically from ISP: Choose this option if your ISP did not assign
a static DNS IP address .
o
Use These DNS Servers: Choose this option if your ISP assigned a static
DNS IP address for you to use. Also complete the fields that are
highlighted white in this section.
o
Primary DNS Server: Enter a valid primary DNS Server IP Address.
o
Secondary DNS Server: Enter a valid secondary DNS Server IP Address.
Configurable Port: This page allows you to assign the functionality intended for
the Configurable Port. Choose from the following options:
o
WAN: If this option is selected, configure the WAN3. The WAN Mode
options are now available as there are two WAN ports for the gateway.
o
DMZ: If this option is selected, you are able to configure the DMZ port
on the DMZ Configuration menu.

Figure 39: WAN3 configuratio n for 3G inte rne t
3G WAN support is available on thes e dual WAN products: DSR-1000 and DSR-
1000N.
Cellular 3G internet access is available on WAN3 via a 3G USB modem for DSR-
1000 and DSR-1000N. The cellular ISP that provides the 3G data plan will provide
the authentication requirements to establish a connection. The dial Number and APN
are specific to the cellular carriers. Once the connection type settings are configured
and saved, navigate to the WAN status page (
Setup > Internet Settings > WAN3
Status
) and Enable the WAN3 link to establish the 3G connection.
3.8 WAN Port Settings
Advanced > Advanced Network > WAN Port Setup
The physical port settings for each WAN link can be defined here. If your ISP account
defines the WAN port speed or is associated with a MAC address, this information is
required by the router to ensure a smooth connection with the network.

The default MTU size supported by all ports is 1500. This is the largest packet size
that can pass through the interface without fragmentation. This size can be increased,
however large packets can introduce network lag and bring down the interface speed.
Note that a 1500 byte size packet is the largest allowed by the Ethernet protocol at the
network layer.
The port speed can be sensed by the router when Auto is selected. With this option the
optimal port settings are determined by the router and network. The duplex (half or
full) can be defined based on the port support, as well as one of three port speeds: 10
Mbps, 100 Mbps and 1000 Mbps (i.e. 1 Gbps). The default setting is 100 Mbps for all
ports.
The default MAC address is defined during the manufacturing process for the
interfaces, and can uniquely identify this router.
You can customize each WAN port’s
MAC address as needed, either by letting the WAN port assume the current LAN
host’s MAC address or by entering a MAC address manually.

Wireless Access Point
Setup
This router has an integrated 802.11n radio that allows you to create an access point for
wireless LAN clients. The security/encryption/authentication options are grouped in a
wireless Profile, and each configured profile will be available for selection in the AP
configuration menu. The profile defines various parameters for the AP, including the
security between the wireless client and the AP, and can be shared between multiple
APs instances on the same device when needed.
The content in this section is applicable to the DSR-500N and DSR-1000N
products.
Up to four unique wireless networks can be created
by configuring multiple “virtual”
APs . Each such virtual AP appears as an independent AP (unique SSID) to suppo rted
clients in the environment, but is actually running on th e same physical radio integrated
with this router.
You will need the following information to configure your wireless network:
Types of devices expected to access the wireless network and their supported Wi-
Fi
modes
The
router’s
geographical region
The security settings to use for securing the wireless network.
Profiles may be thought of as a grouping of AP parameters that can then be applied
to not just one but multiple AP instances (SSIDs), thus avoiding duplication if the
same parameters are to be used on multiple AP instances or SSIDs.

Wireless Settings Wizard
Setup > Wizard > Wireless Settings
The Wireless Network Setup Wizard is available for users new to networking. By
going through a few straightforward configuration pages you can enable a Wi-
Fi™
network on your LAN and allow supported 802.11 clients to connect to the configured
Access Point.
