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 Routing in the Mode field.
Obtain an IP 
Address 
Automatically
Select this if you get a dynamic IP address from your Internet Service Provider 
(ISP). A dynamic IP address is not fixed; your ISP assigns you a different one 
each time you connect to the Internet. 
This option is not available if you select RFC 1483 in the Encapsulation field.
Static IP Address
Select this if your ISP gave you a fixed IP address. Enter the IP address you 
were given in the IP Address field.
IP Address
If your ISP gave you an IP address to use, enter it here.
Subnet Mask 
Enter a subnet mask in dotted decimal notation. 
Refer to the appendices to calculate a subnet mask If you are implementing 
subnetting.
Gateway IP address 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 P-660HWP-Dx 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 Connect 
on Demand. The default setting is 0, which means the Internet session will not 
timeout.
NAT
NAT is the translation of the IP address of a host in a packet, for example, the 
source address of an outgoing packet, used within one network to a different IP 
address known within another network.
None
Select None to disable NAT.
SUA Only
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 to go to the Port Forwarding screen to edit a server mapping set.
