Hello Raj,
You need to configure firewall for allowing communication.
By default firewall will drop all connection.
Things need to be considered while configuring Firewall:
- Configure Internal Interface
- Configure External Interfcae
- Configure Access-list
- Configure NAT/PAT
- Configure default route
Try configuring above and check if firewall is allowing connection.
