Hello Dheeraj,
I have the same problem that you had (timeout in HANA SDA remote source), even though the isql test is successful from the HANA Linux box.
Could you describe which ports did you open in MSSQL?
I've already open the port i'm listening on (1433) in the firewall but it's still not working.
And yes, it's a static port.
Any help would be appreciated.
