LABEL	DESCRIPTION
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
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	Enter a subnet mask in dotted decimal notation.
(ENET ENCAP	Refer to the appendix to calculate a subnet mask If you are implementing
encapsulation only)	subnetting.
Gateway IP address	You must specify a gateway IP address (supplied by your ISP) when you select
(ENET ENCAP	ENET ENCAP in the Encapsulation field
encapsulation only)
DNS Server
First DNS Server	Select Obtained From ISP if your ISP dynamically assigns DNS server
Second DNS Server	information (and the ZyXEL Device's WAN IP address).
Third DNS Server	Select User-Definedif you have the IP address of a DNS server. Enter the DNS
	server's IP address in the field to the right. If you chose User-Defined, but leave
	the IP address set to 0.0.0.0, User-Definedchanges to None after you click
	Apply. If you set a second choice to User-Defined, and enter the same IP
	address, the second User-Definedchanges to None after you click Apply.
	Select DNS Relay to have the ZyXEL Device act as a DNS proxy only when the
	ISP uses IPCP DNS server extensions. The ZyXEL Device's LAN IP address
	displays in the field to the right (read-only). The ZyXEL Device tells the DHCP
	clients on the LAN that the ZyXEL Device itself is the DNS server. When a
	computer on the LAN sends a DNS query to the ZyXEL Device, the ZyXEL
	Device forwards the query to the real DNS server learned through IPCP and
	relays the response back to the computer. You can only select DNS Relay for
	one of the three servers; if you select DNS Relay for a second or third DNS
	server, that choice changes to None after you click Apply.
	Select None if you do not want to configure DNS servers. You must have
	another DNS server on your LAN, or else the computers must have their DNS
	server addresses manually configured. If you do not configure a DNS server, you
	must know the IP address of a computer in order to access it.
Connection
(PPPoA and PPPoE
encapsulation only)
Nailed-Up	Select Nailed-Up Connection when you want your connection up all the time.
Connection	The ZyXEL 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.
Apply	Click Apply to save the changes.
