DESCRIPTION
Select the method of encapsulation used by your ISP from the drop-down list
box. Choices vary depending on the mode you select in the Mode field.
If you select Bridge in the Mode field, the encapsulation type is RFC 1483.
If you select Routing in the Mode field, select PPPoA, RFC 1483, ENET
ENCAP or PPPoE.
Select the method of multiplexing used by your ISP from the drop-down list.
Choices are VC or LLC.
By prior agreement, a protocol is assigned a specific virtual circuit, for example,
VC1 will carry IP. If you select VC, specify separate VPI and VCI numbers for
each protocol.
For LLC-based multiplexing or PPP encapsulation, one VC carries multiple
protocols with protocol identifying information being contained in each packet
header. In this case, only one set of VPI and VCI numbers need be specified for
all protocols.
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for local
management of ATM traffic). Enter the VCI assigned to you.
This option is available if you select Route in the Mode field.
A static IP address is a fixed IP that your ISP gives you. A dynamic IP address is
not fixed; the ISP assigns you a different one each time you connect to the
Internet.
If you use the encapsulation type except RFC 1483, select Obtain an IP
Address Automatically when you have a dynamic IP address; otherwise select
Static IP Address and type your ISP assigned IP address in the IP Address
field below.
If you use RFC 1483, enter the IP address given by your ISP in the IP Address
field.
This option is available if you select ENET ENCAP in the Encapsulation field.
Enter a subnet mask in dotted decimal notation.
This option is available if you select ENET ENCAP in the Encapsulation field.
Specify a gateway IP address (supplied by your ISP).
Select Nailed-Up Connection when you want your connection up all the time.
The Device will try to bring up the connection automatically if it is disconnected.
Select Connect on Demand when you don't want the connection up all the time
and specify an idle time-out in the Max Idle Timeout field.
Specify an idle time-out in the Max Idle Timeout field when you select
Connect on Demand. The default setting is 0, which means the Internet
session will not timeout.
SUA only is available only when you select Routing in the Mode field.
Select SUA Only if you have one public IP address and want to use NAT. Click
Edit Detail to go to the Port Forwarding screen to edit a server mapping set.
Otherwise, select None to disable NAT.
Click this to return to the previous screen without saving.
