I tried add inbound for port 502, but it seem be not enough.

Answer 1

You would need to:

1. Ensure your VM has a public IP
2. Add an NSG rule to allow traffic on port 502 from the internet to your VM]
3. Ensure any firewall on the VM its self allows port 502 inbound

Answer 2

Hello Kvmanh - bkas,

If your end goal to connect to a specific VM by using the Load Balancer frontend IP address and port number, you could create the NAT rule to forward the Traffic to your VM.

Reference: Manage port forwarding for backend pool with Azure Load Balancer.
