I have a situation that requires IIS only respond if the client IP address matches the IIS security's IP address list.
This has worked well for a few years, but the number of clients has increased to a point where adding/removing IP addresses is rather painful...
We would like/prefer to keep this system in place, but wonder if there is an easier way.
Is there a way to install a DDNS client on each client machine, that would update a DDNS entry... then on the server, automatically remove the old IP and add the new IP (or just do the DDNS lookup in real-time and allow based on that)? Any 3rd party apps that might do this or make it easier to admin?
Any alternate suggestions are welcome.
