PuTTY only forwards TCP, and only creates links in one direction. The 
implications for protocols like UDP or services that connect back are 
self-evident.

If you want to forward other protocols (effectively do a VPN) you need 
to do something like a PPP-over-SSH tunnel, which is quite a different 
thing. Unless your UDP traffic buffers lots and/or the entire pipe is 
faster than it needs to be for un-tunnelled traffic, a more complex 
non-TCP solution like IPSec will bring you better results.
