I have several locations that expose resources to over the public network for the purpose of monitoring (cameras, networks, etc.).
I secure access using multiple layers. In addition to the standard user name and login, I also do a reverse DNS check on my firewall to make sure the traffic is coming from either another one of my locations or my mobile phone. To accomplish this on my phone, I would need a dynamic DNS update client for my phone.
I know I can accomplish this by visiting the website and forcing an update, but I would rather have it automated.
Thanks in advance for your help,
