There is a table for filtering the packets (the “filter” table) which can have only rules in the INPUT, OUTPUT, and FORWARD chains. Rules in this table don’t alter the packet in any way.There is a table for NAT (the “nat” table) which uses the chains PREROUTING (for altering ...
As a result, DPI provides a more effective mechanism for executing network packet filtering. In addition to the inspection capabilities of regular packet-sniffing technologies, DPI can find otherwise hidden threats within the data stream, such as attempts at data exfiltration, violations of content po...
The firewall can also be configured to utilize stateful packet filtering which involves caching rule processing results for one or more packets, and then utilizing the cached results to bypass rule processing for subsequent similar packets. To facilitate passage to a user, by a firewall, of a ...
