Local proxy listens on port 3128, 2121, 1080.
I use Putty's proxy option to get ssh tunnel passed through proxy. 
I have to use proxy to make connection outside at all.

If sshd listens on port 22, local proxy's log calls this type
of traffic 'HTTPS' eg 'xxx.xxx.xxx.xxx HTTPS'. I guess, using port 443
wouldn't make any difference, because that's really HTTPS port and
thus would be correctly remarked 'HTTPS traffic' (dumb proxy
server). But i don't know of it, i'll try it out with port 53.

Thanks for the hint! :)
