Sometime we need to access ports from the server which are not open on firewall, for application testing sometime we need more ports then the generic one, lets say one of your server is running 4 applications, two are on ports 80 and 443 which are open on firewall as well but for other two applications, ports are 8905 and 8906.
Now you have two opetions, one, request the firewall opening or open the port using SSH tunnel (make sure you are not breaching your company security policy, I have just listed the way around here and not encouraging any one to use this option untill used with in the security policies of your work place).
to open a SSH VPN tunnel:
1. open putty and enter your server name
2. Under category goto SSH then expand it and goto Tunnel
3. now enter source as your source port from local machine, lets say we opted port 10005
4. now enter destination as techsteppers-labs01:8905
5. save your session and open the puty
6. login into the server with valid credentials
7. now open browser with localhost:10005/application
Enjoy!!!
