-dport refers to the destination port, which is the port on the receiving side of a connection where data is sent. Conversely, -sport stands for source port, which is the port on the sending side of a connection from which data is transmitted. These options are commonly used in firewall rules, like those in iptables, to specify the ports involved in network traffic filtering and management.Copyright © 2026 eLLeNow.com All Rights Reserved.
