Load Balancing Azure origins

Good morning, through load balancing I can reach 2 sources of 2 web servers that reside in our data centers in Italy.
But I can’t reach 2 origins that reside on Azure servers.
Does Azure require a different configuration?
Thank you

Hey,

Thanks for asking.

May I ask if there is some kind of a firewall in between? :thinking:

Are Cloudflare’s IPs allowed to connect?

HI,

Thanks for the reply.

Yes, there is a firewall in between.
At your suggestion I opened the ports in all and actually now the traffic is reforwarded.

I also tried to open traffic from the specific IP released by cloudflare for the LB’s DNS, but the traffic doesn’t pass.

Where do I find the batch of cloudflare IPs needed?

Thank you

Okay,
Now everything works correctly by entering the Cloudflare IP batch.

But I have the problem that I am forced to open not only the 443, but also the 80 to make the service work.

Advice?

Make sure you are using Full (strict) SSL mode in Cloudflare.
