A server stack is the collection of software that forms the operational infrastructure on a given machine. In a computing context, a stack is an ordered pile. A server stack is one type of solution stack — an ordered selection of software that makes it possible to complete a particular task. Like in this post about Using Putty/plink to connect to remote MySQL from Windows machine using Port Forwarding and multi hop SSH tunnel was one problem in server stack that need for a solution. Below are some tips in manage your windows server when you find problem about windows, port-forwarding, ssh-tunnel, putty, plink.
I need to set up port forwarding from my local Windows machine Port 3307 to a remote MySQL server port 3306 but accessed via 2 Linux proxy servers and a Linux web server.
I need to use Putty or plink.exe on the Windows machine to set up the connnection.
See diagram 
I’ve found examples using Putty GUI or plink CLI to achieve similar with only 1 proxy server but not with multiple hops.
I can achieve the connection I need on a *nix machine using
ssh -N -L 127.0.0.1:3307:db-server:3306 -J user@proxy1 user@proxy2 user@web-server
Trying to do the same using Putty or plink.
Update
I ended up using OpenSSH on Windows.
The final command was a little different to above.
ssh -L 127.0.0.1:3307:db-server:3306 -J user@proxy1,user@proxy2 user@web-server -p 31001 -i "C:pathtoprivate-key"
Note we were connecting to the final web server on port 31001, hence the -p 31001.
If there is no explicit requirement to use putty/plink, I would just use Windows built-in ssh for the purpose. It is the same SSH as in Unix.
