I need to create SSH tunnel with PuTTY in Windows, that would do the same as this command in Linux:

ssh -fN -L 2000:SomeIp:2000 myusername@myLinuxBox

I tried many options in PuTTY, including setting source port in GUI to "2000" and destination to "SomeIp:2000". Destination is set to local (as the -L switch suggests).

I successfully login to my SSH box but port forward is not made.

Is this even possible in Windows, so that all the connections made by programs that use this port (2000) will go through this tunnel?

With the PuTTY suite, you can set up a tunnel either using the PuTTY itself (GUI) or using the command-line tool plink.exe.

With the plink.exe, you use the same arguments as with the OpenSSH ssh, except for the -f, which does not have an equivalent in Windows.

plink.exe -N -L 2000:SomeIp:2000 myusername@myLinuxBox

Reference: Using the command-line connection tool Plink

With the PuTTY, the -L 2000:SomeIp:2000 translates to:

So it's actually, what you claim to have tried. If you have any problems, use the PuTTY event log to investigate:

The -N translates to the option "Don't start a shell or command at all".

PuTTY option Don't start a shell or command at all

But it probably does not make sense with a GUI client to enable it, as you get a window anyway, you just cannot do anything with it. See also the PuTTY wish no-terminal-window.
