Multi hop ssh connections with Putty

[Simon Wistow]

I have machine - let's call it 'destination' that I want to ssh to.

Unfortunately I have to do that by first sshing into a machine called 
'intermediate' on port 6464. 

I would like to be able do this automatically in putty by just selecting 
the saved profile for 'destination' and I believe that's possible using 
some combination of the Proxy config panel and possibly plink but I'm 
buggered if I can work it out.

My best guess is to create a new profile for destination with the 
correct username and hostname. Then go to 

Connection -> Proxy 

and select Local and then in 'local proxy command' do

plink intermediate:6464 -n %host:%port

but that doesn't seem to work 

Anybody able to shed some light?
