;

Idle Timeout: Specifies that PPPoE connection should disconnect if the link has no activity

detected for n seconds. This field is used in conjunction with the On-Demand feature and is

enabled only when the On Demand field is checked. To ensure that the link is always active,

enter a 0 in this field.

;

Keep Alive: When the On-Demand option is not enabled, this value specifies the time to

wait without being connected to your provider before terminating the connection. To ensure

that the link is always active, enter 0 in this field.

;

Authentication: The different types of available authentications are:

Auto: When auto is selected, PAP mode will run by default. However, if PAP fails,

then will run as the secondary protocol. This is the default setting.

PAP: Password Authentication Procedure. Authentication is done through username

and password.

CHAP: Challenge-Handshake Authentication Protocol. Typically more secure than

PAP, CHAP uses username and password in combination with a randomly generated

challenge string which has to be authenticated using a one-way hashing function.

;

MTU: Maximum Transmission Unit. The largest size packet that can be sent by the modem.

If the network stack of any packet is larger than the MTU value, then the packet will be

fragmented before the transmission. This can be set from a minimum 128 to maximum 1500.

;

On Demand: Enables on-demand mode. The connection will disconnect if no activity is

detected after the specified idle timeout value. When checked, this field enables the Idle

Timeout field.

;

Default Gateway: If checked, this connection becomes the default gateway to the Internet.

;

Enforce MTU: Check box if you experience problems accessing the Internet over a PPPoE

connection. This feature will force all TCP traffic to conform with PPP MTU by changing TCP

Maximum Segment Size to PPP MTU. MTU (Maximum Transmission Unit) is defined as the

maximum packet size (In bytes), that a particular interface can handle.

;

Debug: Click to enable the Debug function. It is for ISP /testers to simulate packets go

through from WAN side. The complete debugging information will show and listed in the

System Log file.

;

PPP Unnumbered: This is a special feature for telecommunication. It enables PPP

connection to act like a bridge connection. ISP can assign blocks of public addresses to the

client and make the PPP appear as pass-through from WLAn side to the LAN side.

;

LAN: The LAN field is associated with the PPP UNunmbered field and is enabled when the

PPP UNnumbered field is checked. You can specify the LAN group the packets need to go

through when the PPP UNnumbered feature is activited.
