Use Port Forwarder Ultimate to forward internal ports. You can for example run a server on port 2121 and use Port Forwarder Ultimate to make is accessible from the outside on port 21. Because a lot of Android apps have limitation on what port you can run a server on (normally only above 1024) you can use this app to run it on all ports!Root is required, because you need root to change to a port below 1024.Note.
