Port Mapping FAQs
Q: Why do we use port mapping?
A: Port mapping is used to enable external devices or networks to access services hosted on private networks. It allows for remote access, hosting of services, peer-to-peer connections, and enhanced network performance.
Q: What is a port mapping rule?
A: A port mapping rule defines how incoming network traffic should be forwarded. It includes the external port, internal IP address, internal port, and protocol.
Q: What is port mapping vs. port forwarding?
A: Port mapping and port forwarding are closely related terms, but they have distinct differences. Port mapping refers specifically to the process of associating a specific external port with an internal IP address and port within a local network. It ensures that incoming traffic is correctly directed to the intended device or service. On the other hand, port forwarding is a broader term that encompasses port mapping. It involves forwarding network traffic from an external port to an internal IP address and port, allowing external devices to access specific services hosted on private networks.
Port mapping focuses on the configuration of individual ports within a network, while port forwarding encompasses the broader concept of routing traffic to specific devices or services. Both techniques are important for enabling seamless communication and access to services hosted on private networks.
