Strange BIGSHOW,

I think that the problem is in your configuration.
All iphone has the same problems.

Put information about your connection.
1. Are you sure what IP as dest you are using?
2. Are you using Admin password for connection? ( please use simple password for test )
3. Are you using 80 port for connection?
4. Could you do ping test to profilux from iphone ( use freeware Admin app for it )
5. Check that you can connect to 80 port of profilux using telnet app ( use freeware Admin app for it )

Put the screenshot from your configuration on iPhone
