About this app

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. If you find a bug or have a problem please contact us by email since we cannot help you if you post it in the reviews.

**
In this version you can add one server (Port Forwarder or Dynamic DNS Updaters) and three rules per server. If you want to be able to add unlimited items please buy Port Forwarder Ultimate Pro. If you buy the pro version you will support development, will be able to add unlimited items and see no advertisements!
