Network Configuration |
 |
|
WAN Mode |
The WAN mode page allows you to configure how your router uses your external
Internet connections; for example your Broadband port or dial-up modem
connection. |
NAT is a technique which allows several computers on a LAN to share an Internet
connection. The computers on the LAN use a "private" IP address range while the
WAN port on the router is configured with a single "public" IP address. |
Along with connection sharing, NAT also hides internal IP addresses from the
computers on the Internet. |
NAT (Network Address Translation) |
Select
NAT if your ISP has assigned only one IP address to you. The computers
that connect through the router will need to be assigned IP addresses from a
private subnet (example: 192.168.1.0). If your ISP has assigned an IP address
for each of the computers that you use, select
Classic Routing. |
Note: The router will delete all inbound firewall rules when switching between
NAT and
Classic Routing. |
Port Mode |
The Port Mode settings allow you to configure
whether the router should use only one WAN port or both. |
If you are connected to only one ISP, then select
Use single WAN port and select either
Broadband or
Dial-up. |
If you have two ISP links for Internet connectivity, the router can be
configured in
Auto Rollover Mode. |
If you want to use Dial-up as a backup connection then select the
Primary Broadband with
Dialup as backup option. This will set the router
to
Auto Rollover Mode and the router will switch to
dial-up if the broadband connection fails. Ensure that the dialup settings are
configured before enabling this feature. The
WAN Failure Detection Method must be configured to
notify the router of a link failure. |
WAN Failure Detection |
When the router is configured in
Auto Rollover Mode, it checks the connection of
the primary link at regular intervals to detect its status. Link failure is
detected using one of the following ways: |
|
Select
DNS lookup using configured DNS Servers to detect
failure of a WAN link, using the DNS servers configured in the Broadband & Dial-up ISP
Settings pages. |
To use a specific DNS server for detecting WAN failure, select
DNS Lookup using this DNS Server and type in the IP
address of the DNS server. |
To detect a Broadband connection failure by pinging to an IP address, select
Ping to this IP Address and enter an IP Address in the fields under
this option. Ensure that the destination host is reliable. |
The
Test Period field tells the router how often it
should run the above configured detection method. |
To define the number of failures after which the router should roll-over to the
next port, specif the number of attempts in the
Rollover after box. |
