Azure - How to keep up to date valid IP addresses in firewall RRS feed

  • Question

  • Hi all, can you advise, please?

    Azure - We have a network security rule allowing inbound traffic to the virtual network from our web apps based on their IP addresses (Additional Outbound IP Addresses). The web apps were down due to the Azure problems, and when booting changed IP addresses. Then, the firewall blocked the traffic from the web apps, and the system stopped working correctly.

    1. In case WebApp unplanned reboot, due to the problems on Azure side, does the system change WebApp IP address?
    2. How to keep Network Security Group rules up to date with valid IP addresses of the WebApps? So far, we set it once for all by setup script (combination of ARM with bash az commands).

    This happened for the first time after almost a year running the system.
