Hello Deepak,
besides the Management Console (for identifying the SAP system in your NWDS UI), you also need the http port and the P4 port (5xx00 and 5xx04). In a clustered environment, the http port and host from a web dispatcher or load balancer could be required. This, you need to check with your basis team.
But first give the two additional ports a try.
Regards,
Sebastian
