Call Filtering

Netopia Firmware Version 5.4 supports a call filtering mechanism that lets you control which packets cause connections to be established and which packets cause connections to be maintained (that is, to not time out due to inactivity). This feature is part of the Filter Set management component of the firmware. Call filtering makes use of the existing sets of filter rules that can be associated with a connection.

The term connection includes both non-VPN connection profiles for which the remote network is reached through a switched WAN interface, such as Analog or ISDN, and all VPN connection profiles, such as ATMP, PPTP, and IPsec.

The call filtering mechanism is useful if you have a time-limited type of connection. Such a connection may time out during a period of inactivity and may you want it to be re-established or maintained automatically for certain types of traffic.

You manage Filters and Filter Sets in the Filter Sets management screen under the System Configuration menus.
