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
ENCAP 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
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 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
Connect on Demand
. The default setting is 0, which means the Internet
session will not timeout.
NAT 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
