General
Mode
Select Routing (default) from the drop-down list box if your ISP gives
you one IP address only and you want multiple computers to share an
Internet account. 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 Firewall, DHCP server and NAT on the ZyXEL
Device.
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, select either PPPoA or RFC
1483.
If you select Routing in the Mode field, select PPPoA, RFC 1483,
ENET ENCAP or PPPoE.
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.

Virtual Circuit ID VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define
a virtual circuit. Refer to the appendix for more information.
These fields are not available if you set the WAN type to Ethernet.
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.
Select Obtain an IP Address Automatically if you have a dynamic
IP address; otherwise select Static IP Address and type your ISP
assigned IP address in the IP Address field below.
Subnet Mask This option is available if you select ENET ENCAP in the
Encapsulation field.
Enter a subnet mask in dotted decimal notation.
