Aug 19, 2018 - Every computer on the internet has an IP and port address. For a wired (ethernet) connection, double-click “Local Area Connection,” then.
My ASUS router has a a port range option in my port forwarding along with local port. Do I need to use both when port forwarding? I understand that port range is used for forwarding ports within a range, but then what is the point on local port?
Example image
When I port forward ports I use the just the port range leaving the local port empty. Is this the correct way as I have seen people use both the local port & port range for example forwarding the port 443.
In the photo above, it shows the ports 20,21 forwarded in port range, but then just 21 forwarded as a local port. Does this mean the port 20 is forwarded to port 21?
Please help enlighten me
