User Name (PPPoA and PPPoE encapsulation only) Enter the user name exactly as your
ISP assigned. If assigned a name in the form user@domain where domain
identifies a service name, then enter both components exactly as given.
Password (PPPoA and PPPoE encapsulation only) Enter the password associated with the
user name above.
Service Name (PPPoE only) Type the name of your PPPoE service here.
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.
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.
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).

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.
