Delete Azure Firewall - Visual Studio Subscription

Malzahn, Hendrik 20

Hello,

i need help with the following Problem:

I ran out of monthly Credit in Azure with my Visual Studio Subscription. I have n Azure Firewall that i want to delete.

If click on delete, i get the error:

'Azure Firewall firewall1 failed to dereference Firewall Policy
/subscriptions/<my subscription>/resourceGroups/DEV_RG_STORAGEFLEET/providers/Microsoft.Network/firewallPolicies/policy1.'

if i want to delete the policy, i get the error:

Firewall Policy '/subscriptions/<my subscription>/resourcegroups/DEV_RG_STORAGEFLEET/providers/Microsoft.Network/firewallPolicies/policy1' can not be deleted since there are Azure Firewalls using this policy.

So i cant delete the Resources and im going into a huge forcast for the next month..

Can anyone help me ?

Best Regards

Hi Hendrik,

as long the Firewall Policy "policy1" is associated with the Azure Firewall "firewall1", you will not be able to delete it. So you have to disassociate the "policy1" from "firewall1", maybe you have to associate "firewall1" with another policy. Then you should be able to delete the "firewall1" as you have tried it. You could also use CLI Command:

az network firewall delete --name MyFirewall --resource-group MyResourceGroup

If this works for you, please mark this as the answer. Thanks!

Duplicate of my previous answer. Sorry, don't find any possibility to delete it.

I find you have to do two things:

One is the dissociate the policy as described by Tino. You can't delete it while it's associated (you'd think you would be able to), but you can dissociate it from the firewall.

The other is to delete any IP address that's part of the Azure Firewall front-end configuration.

Once I've done that, I can usually delete the firewall.

Another note: if you're just playing around with these things, you're best to put them in a separate resource group and later just delete the whole resource group.

@Malzahn, Hendrik ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you are not able to delete your Azure Firewall and it's associated Policy with a disabled Visual Studio Subscription.

The subscription becomes read-only when it gets disabled.

Your subscription is disabled to protect you from accidentally incurring charges for usage beyond the credit and free services included with your subscription

You will not be charged for the resources while the subscription is disabled.

Your subscription is re-enabled automatically at the beginning of the next billing period and you will have enough credits to remove/delete and adjust your resources.

In case you have a requirement to delete the resources immediately, I would suggest you create a support request.

Hope this helps.

Cheers,

Kapil

i waited for the next Billing Period and reactivated the subscription. The Solution was to delete the Firewall Rules first, then the Policy and last the firewall itself.

Thanks to everyone.
