The VPN connection is only a way to create a (secured) virtual LAN
connection via the internet. Your raspberry will connect to the VPN
server and obtain a local IP address from the server, for instance
10.100.101.1, on a virtual network device (usually /dev/tun0). After
establishing the VPN connection your Raspberry can be reached by an ssh
session to the IP address that was given to it by the VPN server. I
don't think the NAT is a problem.
The only difficulty is that you somehow need to tell the raspberry to
initiate a VPN connection to the server.
