Troubleshooting failed IP group that causes an AzureFirewall to fail

This is the documentation of a problem I encountered at work today, where updating an IP Group failed and caused the AzureFirewall policy associated with the IP Group to go into a 'Failed' state as well.

In my recent case, this happened in a parent/child policy setup. Traffic was still forwarded correctly by the AzureFirewall.

Update Oct. 2023

This procedure also worked in cases where the parent policy (and one AzFW) failed without any ip group failures.

General procedure:

  • Disconnect child from failed parent policy
  • PUT operation to get the parent policy in 'Succeeded' state
  • (optional, if needed) PUT operation to get the AzFW in 'Succeeded' state
  • If everyhting is in 'Succeeded' state, attach child to parent policy again
