Answer 1

Hello Hamilton O'Biecunas,

Thank you for posting in Q&A forum.

Here are some steps you can try to troubleshoot the issue:

1. Make sure that the load balancer is correctly configured to handle traffic between the VNets. This includes setting up the backend pool, health probes, and load balancing rules. You can refer to the Azure Load Balancer documentation for detailed steps on configuring the load balancer.
2. Verify that the VMs behind the load balancer are responding to health probes. If the VMs are not responding, they will not participate in load balancing. You can troubleshoot this by checking the VM's health and ensuring that the probe port is open and listening.
3. Ensure that the NSGs are not blocking traffic between the VNets. You may need to create rules to allow traffic on the required ports.
4. Since you mentioned that peer-to-peer is running, ensure that VNet peering is correctly configured and that the VNets can communicate with each other. This includes allowing forwarded traffic and gateway transit if needed.
