DESCRIPTION
Select this to activate the WAN configuration settings.
Specify a descriptive name of up to 15 alphanumeric characters for this
connection.
Select Bridge when your ISP provides you more than one IP address and you want
the connected computers to get individual IP address from ISP's DHCP server
directly. If you select Bridge, you cannot use routing functions, such as Firewall,
DHCP server and NAT on traffic from the selected LAN port(s).
This field is not available if you select Bridge 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.
Select the method of multiplexing used by your ISP from the drop-down list box.
Choices are:
• LLC/SNAP-BRIDGING: In LCC encapsulation, bridged PDUs are encapsulated by
identifying the type of the bridged media in the SNAP header.
• VC/MUX: In VC multiplexing, each protocol is carried on a single ATM virtual
circuit (VC). To transport multiple protocols, the Zyxel Device needs separate
VCs. There is a binding between a VC and the type of the network protocol
carried on the VC. This reduces payload overhead since there is no need to
carry protocol information in each Protocol Data Unit (PDU) payload.
