5.4.3.1 Enable/Disable Idle Timer Filter
All Traffic will reset Idle Timer (ignore filter below): Selecting this option will disable the PPP Idle
Timeout filter and allow any traffic through any protocol or port to reset the idle timer. The only dependency
is that the traffic must correspond with the Filter Application (Inbound and/or Outbound). For example, if
Outbound Traffic Only is selected, only traffic in the outbound direction will reset the idle timer. When this
option is selected, all user configured criteria (displayed in the filter table) is bypassed.
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.

Note
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.
