DSL
VPI
and
VCI:
These need to be filled in for the router to be able to communicate with
your Central Office (CO) via DSL. VPI (Virtual Path Identifier) and VCI (Virtual Circuit
Identifier) identify the route that the ATM cells take to reach the CO.
Modulation:
This specifies the DSL modulation: Multi-Mode, T1.413, G.DMT (G.992.1),
or G.LITE (G.992.2). In Multi-Mode, the router automatically detects the modulation.
To save the settings, click on Save. If you have made a mistake, you can click on Reset
to start over.
Advanced Setup – Network
The Network screen allows you to configure your router's client side (Local Area
Network, or LAN) properties. This allows you to modify the router's LAN IP address and
the method of routing to use. Apply changes with care, since they could affect other
clients connected to the router.
LAN IP Address and Network Mask:
These fields set the IP address and mask of the
router on the client side. These are the connection parameters that your PC uses to
communicate with the router.
Host Name:
Some ISPs require your router to be uniquely identified by a host name.
DHCP server:
Click on Enable if you want your router to run a DHCP server to
dynamically assign IP addresses to client machines.
IP Range:
Specifies the range of IP addresses that the router may assign to clients
requesting an IP address.
Lease Time:
Duration (in hours) for which the assigned IP address remains valid When
the IP address expires, the client must renew it.
Routing without NAT:
This method requires each client connected to the router to have
a True IP address. The router maps this IP uniquely with a client and routes traffic
appropriately.
Routing with NAT:
This method supports both True and Virtual IP addresses for clients.
The router maintains a table of virtual IP addresses and port numbers. The combination
of these two uniquely identifies each client.
Bridging:
Selecting this method causes the router to function as a simple bridge with no
routing functionality.
