Westell Dual Connect NAT Router with DMH Technology
User Guide
security, Medium security, allows customization through NAT configuration, so
you can enable the traffic that you want to pass.
Low The low security setting will allow all traffic except for known attacks. With
low security, your Router is visible by other computers on the Internet.
Custom Custom is a very advanced configuration option that allows you to edit the
firewall configuration directly. Only the most expert users should try this.
Home Page
The home page gives you a quick summary of the Router’s state. The following settings are displayed.
Home Page
Connection Overview The Connection Overview section displays the status of the DSL connection.
The DSL must show a state of “UP” in order for the Router to communicate
with your service provider’s network.
Connection Name The Connection Name section displays all of the connection profiles that are
defined by the Router. A connection profile is information that the Router needs
to establish a connection to your ISP. The “PPP Status” columns will show a
status of “UP” if the Router is currently using that profile to communicate. The
command button allows you to control the connection state.
Profile Editor Selecting the “Profile Editor” link will allow you to define or change any of the
connection profile settings.
LAN Configuration
This screen contains the setting that controls how the Router interacts with the local devices connected to the Router.
Westell does not recommend that you change these settings. The following settings are displayed.
LAN Configuration
Router IP Address This controls the IP address that the Router uses for local communication.
Subnet Mask This setting specifies the subnet mask to use to determine if an IP address
belongs to your local network.
DHCP Start Address This setting specifies the start of the IP address pool that the Router uses to
assign IP addresses to local devices.
DHCP End Address This setting specifies the end address of the IP address pool used for automatic
configuration of local devices.
DNS Server Enable DNS stands for Domain Name System. This is an Internet standard that
facilitates communication among devices. This allows a name to be used when
specifying a device instead of an IP address. Normally you want this enabled.
DHCP Server Enable DHCP stands for Dynamic Host Configuration Protocol. This is an Internet
standard that allows the Router to automatically assign IP addresses to devices
connected on the LAN network. It is advised that this opt ion is set to Enabled.
