Allow access to Azure Services equivalent for Azure Web Apps

We have IP address restrictions set on an Azure Web App. These work fine for applications from various locations calling into Azure for a Web App.

We now want to extend these to allow Azure services to access this resource but I cannot seem to get this working. On some other Azure resources (e.g. Azure SQL) there is a button to press that allows access from other Azure services but this does not exist on the Web Apps.

I've also tried:

  • Adding the outbound IP addresses to the firewall.
  • Adding all the IP addresses in the known outbound IP Addresses for the region.

Couldn't find any information on what the IP address range should be between two Azure services.

I'm quite sure you need to whitelist the whole Azure region service is in (we are talking PaaS, for IaaS you can whitelist specific Ip addresses), or at least the service you are interested in (if it has its ranges published somewhere) – 4c74356b41
Yeah I was looking for ranges but the ones I've found didn't seem to work – Daniel Edwards
you saw this json feed with service tags? microsoft.com/en-us/download/details.aspx?id=56519 – 4c74356b41
Yes, that's the one I tried. Specifically I added AppService.UKWest IP addresses listed and none of them worked. – Daniel Edwards
so what are you trying to achieve, exactly? – 4c74356b41

if you want to another Azure web app(B) to access your Azure web app(A) which mapped white list, you can just add out-bound IP of web app B into A's white list .You can find B's out-bound IP here : enter image description here

I have did a quick test between two Azure web apps using webjobs http calling and it works for me.
