DESCRIPTION
Select Router from the drop-down list box if your ISP allows multiple computers to share
an Internet account.
If you select Bridge, the Device will forward any packet that it does not route to this
remote node; otherwise, the packets are discarded.
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 Router in the Mode field, select PPPoA, RFC 1483, ENET ENCAP or
PPPoE.
If you select Bridge in the Mode field, method of encapsulation is not available.
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.
If you select Enable, the Device can connect to IPv4 and IPv6 networks and choose the
protocol for applications according to the address type. If you select Disable, the Device
will operate in IPv4 mode.
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 Router 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.
Enter a subnet mask in dotted decimal notation.
Specify a gateway IP address (supplied by your ISP).
Enter the primary DNS server's address for the Device.
Enter the secondary DNS server's address for the Device.
SUA Only is available only when you select Router in the Mode field.
Select SUA Only if you have one public IP address and want to use NAT. Otherwise, select
None to disable NAT.
Click this to save your changes.
Click this to return to the previous screen without saving.
Click this to display more fields in this screen to configure more details of your WAN
settings.
Select the RIP Direction from None, Both, In Only and Out Only.
This field is not configurable if you select None in the RIP Direction field.
Select the RIP Version from RIP-1, RIP2-B and RIP2-M.
