Hi,One of my clients is a major bank. We need to exchange data a few times a day at different intervals, and they're insisting that we initiate the VPN on demand with relevent traffic. It works from their end. Tunnel is down, they send a ping, first packet is dropped as the tunnel is brought up, subsequent traffic reaches its destination.
It's called "port knocking". Google is your friend here.
