I would like to create a VPN client and VPN server using WCF through HTTP.
Can this be accomplished?
To be transparent you will need to write a driver. But if you just want a tunneling proxy it is easy enough to write. If you use a Session Required Contract with a call back event you can build the tunnel.
Sorry I cannot provide a working example at this time. But I will make a note to cleanup project I have and blog about it later.
Edit...
I took down the site with my example a few years back... if I remember I will track down the code and post it to github.
