Disconnect Timeout: The Disconnect Timeout allows you to set the specific period of time, in minutes, to
disconnect from the ISP. The default is 0, which means never disconnect from the ISP.
Range: 0-32767 Default: 0
PPP Idle Timer Config: It will link you to the PPP Disconnect Timer Configuration page (see Section
5.4.3).
MRU: The MRU (Maximum Receive Unit) field indicates the maximum size IP packet that the peer of PPP
connection (this device) can receive. During the PPP negotiation, the peer of the PPP connection will
indicate its MRU and will accept any value up to that size.
Range: 0-32767 Default: 1492
MTU: Maximum Transmission Unit (MTU) is 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. During the PPP negotiation, the peer of the PPP connection will indicate its MRU and will
accept any value up to that size.
Range: 0-32767 Default: 1492
MSS: Maximum Segment Size is the largest size of data that TCP will send in a single, unfragmented IP
packet. The LAN client and the WAN host will indicate their MSS during the TCP connection handshake.
Range: 0-32767 Default: 1432
Lcp Echo Interval: It is the time interval, in seconds, between PPP session connection attempts.
Range: 0-32767 Default: 10
Lcp Echo Maximum Consecutive Failure: It is the number of times a PPP session can fail while trying to
connect before stopping. If a PPP session fails this number of times, you must manually reconnect the PPP
session.
Range: 0-32767 Default: 6
Authentication: The different types of available authentications are:
l
Auto (default): When auto is selected, PAP mode will run by default. However, if PAP fails, then
CHAP will run as the secondary protocol. This is the default setting.
l
PAP: Password Authentication Procedure. Authentication is done through username and password.
l
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.
Automatic Reconnect: When it is checked, the Router will reconnect a PPP session when it is terminated
by the ISP. If a PPP session is terminated under any other conditions (i.e. by Disconnect Timeout or
manual disconnect), the Automatic Reconnect will not reconnect the session. This box is unchecked by
default.
PPP Configuration Status: A table will be displayed at the bottom of this page to show all related
information of PPP configuration.
5.4.3 PPP Disconnect Timer Configuration
The PPP Disconnect Timer Configuration page enables you to configure what action will bring a PPP
Session out of the Idle state (disconnected state) and reset the Idle Timer. This is done by specifying
criteria contained in packets, namely IP Protocol and Port. The Idle Timer refers to the Disconnect Timeout,
specified on the
PPP Configuration page.
The PPP Idle Timer is recommended to be disabled (
Disconnect Timeout = 0 on PPP Configuration page)
if you want an always-on connection. PPP Disconnect Timer Configuration is intended for users who do
not desire an always-on connection and/or their ISP charge by connection time.
