IŽll just repeat the answer I received back from TeamViewer some time ago:
Thank you very much for your feedback.
You can use the LAN feature. You can set this option by going to Extras-> Options-> Incoming LAN connections.
If you have any further questions, please feel free to contact us again.
P.S. we recently released Version 8 Beta. It offers new features and enhancements.
Please Feel free to download and provide any feedback.

b.t.w. I am running a D-Link router...
P.S. You could also try PocketCloud which I belive also runs on a LAN.
