5. Unless your ATM PVC is set on RFC1483 Bridged mode, you can check NAT box to enable NAT function.
6. If you are using PPP configuration mode, you need to fill in the user name and password and you can set the
PPP session to Dial on demand or Always on mode.
The parameters are described as below:
VPI (Virtual Path Identifier)
: Identifies the virtual path between endpoints in an ATM network. The valid range is
from 0 to 255.
VCI (Virtual Channel Identifier)
: Identifies the virtual channel endpoints in an ATM network. The valid range is
from 32 to 4095 (1 to 31 is reserved for well-known protocols).
ATM Service Type
: Currently, the ADSL Router supports the
UBR (Unspecified Bit Rate)
service type.
PCR (Peak Cell Rate):
Specify the PCR cells per second.
Encapsulation Type:
There are two types for your choosing, VC MUX or LLC/SNAP. Select the encapsulation
based on the setting of the ISP. Consult your ISP for this information.
Local WAN IP Address
: On Router mode, selecting
None
means you have public LAN IP address setting. If you
select
Specify an IP address
, you can specify a WAN IP provided by ISP for your router. If
Server assigned IP address
is selected, the router will get a dynamic WAN IP address
whenever it connects to the remote server or ISP.
Note: If a fixed WAN IP is entered, note that this IP address and the subnet mask could not
be the same with the public LAN interface.
Enable NAT on this interface
: If your LAN interface is set on primary LAN you should check the box of the Enable
Network Address Translation. NAT translates a private IP within one network to a public IP
address.
User Name/Password
: The user name and password used to access the remote server or ISP.
Dial On Demand
: If checked, under disconnected status, if any client PC sends out request for connection, the
ADSL Router will dial the ISP automatically. In this case, if the system administrator wants
to disconnect the PPP session, just click the
Disconnect
button at Quick Start page.
Always On:
Enabling this feature will send echo request to ISP. This prevents the connection from being
hung up by ISP.
The parameters for PPPoE configuration are generally the same as those of PPPoA. The
additional parameters are:
Service Name
: Enter the name of your PPPoE service here.
Service Server
: Enter the name of your PPPoE service server here.
