What is the purpose of port forwarding?
- Port forwarding allows an internal user to reach a service on a public IPv4 address that is located outside a LAN.
- Port forwarding allows users to reach servers on the Internet that are not using standard port numbers.
- Port forwarding allows for translating inside local IP addresses to outside local addresses.
- Port forwarding allows an external user to reach a service on a private IPv4 address that is located inside a LAN.
Explanation: Port forwarding allows a user or program from outside to reach services inside a private network. It is not a technique that allows for using services with nonstandard port numbers. NAT or PAT convert inside IP addresses to outside local addresses.
