Port forwarding is an excellent way to preserve public IP addresses. It can protect servers and clients from unwanted access, “hide” the services and servers available on a network and limit access to and from a network. Port forwarding is transparent to the end-user and adds an extra layer of security to networks.

Is port forwarding legal?

What IP do I use for port forwarding?

In order for port forwarding to work, you'll need to set a static internal IP address (ipv4) for your device. By default, your ipv4 address is probably dynamic, which means it's always changing, so the port forwarding won't be able to pin down your device on your home network.

Should I forward port 80?
