Hi @Krishna, Vamsi

for external access to work, you have to create inbound rules in the network Security Group

You need to create a rule on NSG, for ports you want to Publish to Internet:

Answer 2

Hello @Krishna, Vamsi ,
As I understand, you are able to telnet to the RHEL VM, but unable to establish SSH connection. This actually means that there is either an issue with the SSHD daemon/service.
Please ensure you check if the SSHD daemon in in active state or not. Secondly, check which port is configured in the sshd_config file.
Also, let us know the exact error (screenshot would help) when you are trying to SSH to the VM.
Thanks.
Check that SSH service is running
Check which port SSH is running on
