It then expands on the requirements, for such a solution. Manual configuration of all possible tunnels is too cumbersome in many such cases. In other cases the IP address of endpoints change or the endpoints may be behind NAT gateways, making static configuration impossible. The Auto Discovery VPN solution will address these requirements.}, }
