Daniel Hutmacher shares a couple scripts:
Recently, my home ISP has started changing my public IP address. This causes me some headache because I have a couple of Azure Network Security Group rules (think of them as firewall rules) that specifically allow my home IP access to all of my Azure resources. When my home IP changes, those rules have to be updated accordingly.
So I made a PowerShell-based solution to automatically maintain them.
Read on for the process.
