Created a Ubuntu 14.04 LTS VM in Azure Resource Management Group (ARM). Added few ports to Inbound security rules (for example 9220, 6789, 6980), out of these ports, only 9220 (along with default enabled ports – 22, 80) is working and all other ports are not working. NSG is perfectly associated with the NIC & subnet, no luck and even created a new NSG & associated with same NIC & subnet, still no luck. Ubuntu Firewall is disabled by default.Screenshot of NSG

After install splunk on Azure windows VM, we just need add port 8000 to Azure NSG inbound rules and add port 8000 to windows firewall inbound rules, then we can browse it via the internet.
Azure NSG inbound rules:
Azure VM windows firewall inbound rules:
Then we can browse it via the internet:
To troubleshoot this issue, maybe we can follow those steps:
1.Turn off VM windows firewall(for test, after complete, turn it on)
2.Remove the subnet NSG.
3.Make sure your public IP address is 131.203.112.66
4.Make sure your Local network firewall not block the network traffic. Or Change another network to test it.
Also you can create another Azure VM to test it. Browse splunk with public IP address and port 8000.
Sounds that you have configured everything that is needed but always good to verify from Microsoft tutorials
You have opened your NSG for your load balancer probes but have you also created an NSG rule to allow traffic from the client that initiate traffic against you VM?
