Web Server Host IP/Port Addresses Filtering

If the capture traffic presented to the DNCA is served by multiple web servers via their respective host IP/Port addresses, then each DNCA instance can filter for a subset of those host IP addresses. This method provides the means to distribute traffic loads across the multiple instances.

Note: IP filters are listed in the order in which you enter them, and the order cannot be dynamically changed. However, when the filters are compiled into binary format, they can be collated by address and netmask for optimal processing, though unlikely. Periodically, the list of filters must be reviewed to verify that all active filters contain traffic. Filters without traffic must be removed from the list.

For each instance of the DNCA, the Instance List and Ignored Traffic sections identify the network packets to include and exclude. If the packet matches the required traffic and does not match the traffic to ignore, then capture it for further processing.

In the Filter Rules section, you can specify the IP addresses/ports that are submitted data to the DNCA. You can add and delete specific IP addresses or a range of IP addresses. You can also specify specific hosts whose traffic you do not want the device to capture.
