IP range for Azure Load Testing to whitelist for cloudflare

Question

Hi,
I am currently working on shortlisting potential cloud-based load testing solutions for one of our clients. As part of our evaluation process, we are keenly interested in exploring the capabilities of the Azure Load Testing platform.

Client have enabled Cloudflare DDoS Protection & Mitigation and are unable to disable it during the testing period. Consequently, we need to ensure that the loadGens created by the Azure Load Testing platform are granted whitelist access to conduct our performance testing without any hindrance.

Is there any way to get the IP range of the loadGens generated by the Azure Load Testing platform before the test commences? This information will enable us to configure the necessary whitelisting measures and proceed with our testing with confidence.

Hi

see article here:

https://techcommunity.microsoft.com/t5/apps-on-azure-blog/load-test-endpoints-with-access-restrictions-using-azure-load/ba-p/3610412

You can use VNET injection with Azure Load Testing and route the test traffic through a NAT gateway, which will give you IP's required for whitelisting with Cloudflare.

Hope this helps,

Thanks
