​IP Port Forwarding

IP Port Forwarding is a network configuration that can be enabled to direct packets from one network interface to another network interface, using the destination IP address. When IP Port Forwarding is enabled, the system can route data between different networks, and act as an intermediary for network traffic.

IP Port Forwarding allows routers and network devices to direct traffic between different networks. However, IP Port Forwarding can indirectly impact performance, depending on the efficiency of the routing process, the hardware capabilities of the network devices, the routing protocols used, and the overall network design.

Windows OS supports IP Port Forwarding. However, it is disabled by default, because most consumer-oriented systems do not require routing capabilities. To use the IP Port Forwarding capabilities, you must enable IP Port Forwarding in the Windows OS.

To manage IP Port Forwarding:

1. ​View the current settings: Get-NetIPInterface | Select-Object InterfaceAlias, Forwarding
2. ​Enable IP Port Forwarding: Set-NetIPInterface -InterfaceAlias <Adapter Name> -Forwarding Enabled
3. ​Disable IP Port Forwarding: Set-NetIPInterface -InterfaceAlias <Adapter Name> -Forwarding Disabled
