Hi Mitang,
We would need some more details about your setup before we can guide you toward a solution. What kind of firewall do you have in front of this server and what version of software does it run? What type of configuration have you already done to get this to work? What do the firewall logs show when you try to connect?
In general, you'll usually need to ensure you have the correct permissions (i.e. ACLs), translations (i.e. NAT), and routes in place to get this traffic through the firewall. For example, on the ASA platform running 8.2 or older, you would probably need at least the following configuration:
! Permissions
access-list outside_access_in permit tcp any host
eq ssh access-group outside_access_in in interface outside
! Translations
static (inside,outside)
netmask 255.255.255.255
Hope that helps.

Hi Mitang,
Can you start by sharing the output of 'packet-tracer in outside tcp
Also, please let us know what syslogs are generated when the connection fails.

Hello Mitang,
In addition to above metioned, please share the following:
1) public IP of workstation from where you are trying to access
2) output of "show run ssh"
3) version of ASA code running
Hope this helps. Please reply back if you need any further assistance.
