Before going farther, you need to a bit more defining of the problem
you want to solve, as well as the technology. I think of VPDN as
virtual private dial network, so where is the dialing if you are
running over the Internet? To the ISP?
Are there other kinds of data not requiring security that need to go
over the same tunnels, which would be a reason for GRE?
Where is the IPSec encryption taking place? Hosts? Your gateways? ISP gateways?
