Dear Thierry,
It works great but now I've got another problem, I'm trying to compile GNAP with nylon, a sock proxy and the following error occurs:

extensions: nylon

This is also possible to do without a bridge, using OpenVPN 2.0 "server"
mode. See http://openvpn.net/howto.html

GNAP vanilla kernel is missing bridge support.

USE_VPN triggers the use of OpenVPN. It supports both modes.
