Encapsulation

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 

 or PPPoE.

Multiplexing

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.

VPI

The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.

VCI

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.

IP Address

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 

 when you have a dynamic IP address; otherwise select 

 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.

Subnet Mask 

This option is available if you select ENET ENCAP in the Encapsulation field.

Enter a subnet mask in dotted decimal notation. 

Default Gateway

This option is available if you select ENET ENCAP in the Encapsulation field.

Specify a gateway IP address (supplied by your ISP).

Connection
Nailed-Up Connection

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.

Connect on Demand

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.

Max Idle Timeout

Specify an idle time-out in the Max Idle Timeout field when you select 

. The default setting is 0, which means the Internet 

session will not timeout.

NAT

 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 

 to go to the Port Forwarding screen to edit a server mapping set. 

Otherwise, select None to disable NAT.

Back

Click this to return to the previous screen without saving.
