Lol I do understand. That is why like I mentioned earlier the HDR would discover the IP and email to a chosen email address periodically.I really don't think you understand:
1. Your IP changes every few days. You are in Spain. All you have is internet access.
2. To get to your HDR you need to determine what the current routable IP is. The only way to do this is for an external server or service to know it.
3. Some external service is always needed, it is just not possible to solve this totally on a HDR connected to a dynamic IP.
Hence the package provides a client which works with dynamic dns servers. (there may also be a client in your router, but usually no choice of provider).
