Only filtered traffic will reset the Idle Timer (use filter below): Selecting this option
will enable the PPP Idle Timeout filter and only allow traffic specified in the filter table to
reset the idle timer. The traffic specified in the filter table must also correspond with the
Filter Application selection. For example, outbound traffic with criteria matching that of
the filter table will only be allowed to pass if either
Outbound Traffic Only or Inbound
and Outbound Traffic is selected.
PPP reconnect on WAN access must be enabled for the Idle
Timer to reconnect a PPP Session when a request is made
from the LAN to the WAN.
5.4.3.2 Filter Application
The Filter Application consists of three options that determine which sources (LAN and/or
WAN) will be able to reset the Idle Timer and reconnect the PPP session.
Inbound Traffic Only: Selecting this option will allow PPP requests from the WAN side
to reset the Disconnect Timeout timer. Note that requests from the WAN side cannot
bring a PPP Session out of Idle state. This is because when a PPP Session is in Idle
state, the connection is down (if they match the filter table criteria).
Outbound Traffic Only (default): When this option is selected, PPP sessions can only
be activated (Idle Timeout) when a request is made on the LAN side to the WAN side.
The disconnect timer will reset when outbound traffic is detected (if they match the filter
table criteria).
Inbound and Outbound Traffic: Selecting this will allow both WAN and LAN source
packets to reset the idle timer.
5.4.3.3 Filter Details
The table displayed in the Filter Details section of the page shows all the current Idle
Filters. Traffic must match the criteria of one of these filters in order to cause an Idle
Timeout, unless
All Traffic will reset Idle Timer is selected. As a default and starting
point for configuration, WWW browsing (HTTP), FTP, and Telnet related packets are part
of the filter table.
IP Protocol: It is the IP Protocol name corresponding to the Protocol Number.
