Welcome to the Apple community.
You don't need an Internet connection in order to display a presentation from an iPad on an Apple TV. I have no idea where you have got this information from.
The reason you and cannot work through a proxy with an Internet connection, is to stop movies rented or purchased from the iTunes store being watched on a whole bunch of Apple TVs

Keynote presentations, are mirrored from the iPad via airplay (iPad 2 or better), the only requirement for airplay is that both devices are on the same network and that airplay is enabled on the Apple TV itself.
