Assign a static IP address to an AWS Application Load Balancer

I have a load balancer created in my VPC with two subnets. Now I want to open a firewall rule from within my company intranet. I have no control over this firewall. But to open a rule on the firewall - the firewall team is accepting only ip addresses and not the DNS names.

But since the IP address of the load balancer keeps changing I can't give it to the firewall team. That's where I am stuck.

How can I open a firewall rule to an AWS load balancer from within my intranet?

You are correct that an Application Load Balancer does not provide static IP addresses.

You might be able to change to a Network Load Balancer:

Elastic Load Balancing creates a network interface for each Availability Zone you enable. Each load balancer node in the Availability Zone uses this network interface to get a static IP address. When you create an Internet-facing load balancer, you can optionally associate one Elastic IP address per subnet.

It is also possible to put a Network Load Balancer in front of an Application Load Balancer to gain the benefits of both.
