Samples/Time Between Changes Write security: 3; Read security: 5

This value is the minimum time between bandwidth changes for this Connec- tion List profile. The range is 0 to 255 seconds. The default is 60 seconds.

Connection List/Filters

The Express XL/XLT can block packets in and out of a WAN port by use of the filters. These filters are set up on a per-Connection List profile basis. They are set up in two steps: 1) define the types of packets that would be of interest in the Configuration/Security/Filter Defines menu, and 2) set up the filter type and combination of defines that will cause a packet block.

Typical example of a filter setup:

Filters/WAN-to-LAN (In)

Write security: 2; Read security: 5

The packets which come into the Express XL/XLT can be filtered in three ways:

Disabled (def) - Turns off packet input filtering. No incoming packets are blocked.

Block All - All incoming packets from the WAN are blocked except as defined in the Filters/In Exceptions list.

Forward All - All incoming packets from the WAN are not blocked except as defined in the Filters/In Exceptions list.
