The firewall determines if a packet is the first packet of a new session or if a packet is part of an existing session using which kind of match?
The firewall typically uses a 5-tuple match to determine if a packet is the first packet of a new session or part of an existing session. The 5-tuple includes the Source IP Address, Destination IP Address, Source Port, Destination Port, and Protocol. This combination is sufficient to uniquely identify a session in network communications.
