Description: Port forwarding is a technique used to allow external devices to access services on a private network. This process involves redirecting connection requests from a specific port on a router or firewall to a different port on a device within the local network. This is particularly useful in environments where access to applications or services behind a NAT (Network Address Translation) or firewall is desired, such as web servers, game servers, or IP cameras. Port forwarding is typically configured on the router or firewall, where the external port to be used for the connection and the internal port to which traffic should be directed are specified. This technique is fundamental in both LAN and WAN networks, as it enables communication between devices on different networks, facilitating various applications and services. Additionally, in cloud environments, port forwarding can be crucial for resource management and the security of applications deployed in a Virtual Private Cloud (VPC).
