A packet filtering firewall restricts network data entry and exit. This security strategy regulates packet flow using rules, protocols, IP addresses, and ports. Packet filtering prevents network intrusion. IP networks transport-independent data packets. Unless they fulfill predefined filtering criteria, the small packets are deleted. A packet filtering firewall may offer adequate security by using network-layer filtering rules.

The firewall checks source and destination IP addresses. ACL controls IP packet ports, sources, destinations, and protocol IDs. The firewall verifies the IP, TCP, or UDP header data to allow or refuse a packet.
