First DNS Server

Select From ISP if your ISP dynamically assigns DNS server information (and the

ZyXEL Device's WAN IP address). The field to the right displays the (read-only)

 

DNS server IP address that the ISP assigns.

Select User-Definedif you have the IP address of a DNS server. Enter the DNS

 

Third DNS Server

 

 

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 None if you do not want to configure DNS servers. If you do not configure a

 

 

DNS server, you must know the IP address of a computer in order to access it.

 

WAN MAC Address

The MAC address section allows users to configure the WAN port's MAC address

 

 

by either using the ZyXEL Device’s MAC address, copying the MAC address from

 

 

a computer on your LAN or manually entering a MAC address.

6.3.2 PPPoE Encapsulation

The ZyXEL Device supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection using PPPoE.

For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius).

One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals.
