This app was made to forward inbound connections from internet through your android device to a PC. More Information on Port Forwarding or Port Mapping technique can be found on en.wikipedia.org/wiki/Port_forwarding

CAUTION:
Providers may block inbound connections per default. For use with your public IP please clarify if you are behind a NAT or firewall. Your provider may allow you to disable the firewall. If you can ping the public IP from internet you are good to go!

This app allows you to forward a public network port to one target host of your tethered network. For example, Port Forwarder can be used to play LAN games over USB Tethering. This can also be used as connector for a mobile web-server (PC) if your android phone has a public accessible IP.

Port Forwarding Features
– UDP
– TCP
– supports portable Wi-Fi hotspot
– supports USB tethering
– throughput information
– runs as android service
– no su or root required
– does not suppoer port ranges

If you feel like this app does not work please do not hesitate to contact me. But before you do that please try to ping your public IP from the internet to proof your IP is accessible for inbound connections.

Public accessible IP:
Providers may usually protect your device by keeping off any internet connections coming from the outside (inbound connections). So by default you may not be able to host any public service on your device. However, providers may allow you to disable this protection on their website. If you change that, please be aware of the risk.

Thank you for all your feedback so far! I hope we could fix bugs.
If you want to get involved in this project please do not hesitate to contact us. We are searching for an reach-ability tester service to verify whether an IP is accessible from internet or not. If somebody could offer such as a web-service this would be greatly appreciated.

This app does not support ports below 1024 (privileged ports). Please use higher port numbers on this device instead. The target port does not have this restriction.

This app does not allow you to enter ranges of ports.
