To use protocols with ports below 1024 your device requires root privileges. HosTaGe does not run with root privileges by default. That is why a small program called Portbinder is needed that opens a socket and passes it to the main HosTaGe App.
Another technique is to redirect those ports to higher port numbers. This is achieved using Android\'s iptables. If iptables is available on your device the Portbinder is not required.
