DESCRIPTION

 

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.

 

 

 

 

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

 

 

 

 

 

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

Select Connect on Demand when you don't want the connection up all the time

 

Demand

and specify an idle time-out in the Max Idle Timeout field.
