i have a unique setup.
I have 2 SQL instances that are on VM's in Failover Cluster that work with a dual ip internal load balancer. ( each instance is on different health probe ports)
I am now needing to NAT/map/Associate public IP's for 1433 sql access from certain customers.
So is there any way to associate/nat a public ip to each of those 2 Internal load balancer Ip's?
Hi,
No, an Azure Internal Load Balancer can only have a private IP address.

I am aware that i can't do it directly. i was wondering if there was some way to NAT to the ip address that the load balancer
When an internal Standard Load Balancer is used, you need to take steps to create outbound connectivity for the VMs in the backend pool if outbound connectivity is desired.
what about using azure firewall to NAT an external ip?
and do you have docs to create that outbound connectivity?
I'm not sure if there are guide docs for what you're seeking exactly, but here's something to get you started:
Configure load balancing and outbound rules in Standard Load Balancer by using the Azure portal
https://learn.microsoft.com/en-us/azure/load-balancer/configure-load-balancer-outbound-portal
Create an internal load balancer by using the Azure PowerShell module
https://learn.microsoft.com/en-us/azure/load-balancer/load-balancer-get-started-ilb-arm-ps
You may create a new thread and ask in the dedicated forum over here:
https://learn.microsoft.com/en-us/answers/topics/azure-load-balancer.html
p.s. the firewall works
Do you have documentation on performing those steps to create outbound connectivity on vms from the internal load balancer?
Greetings,
For now there is no possibility of assigning Public IP to an Azure ILB. Also there is a feature request which got declined indicating that there are no plans to implement this feature in ILB. In order to establish public communications you need to deploy standard public load balancer.

you have to deploy a public load balancer to give vms that are on an internal load balancer external connectivity??
