I may me missing something, but won't doing a normal ssh give you the X
forwarding you need, even if it is behind a proxy?

I believe that X11 forwarding isn't on by default (in OpenSSH anyway), so
you'd need to have these lines in /etc/ssh/ssh_config:

   ForwardAgent yes
   ForwardX11 yes

and similar in sshd_config as well.

Is that OK or did I miss something?

The other followup to this post had mention of using 'xhost', but that
shouldn't be necessary with a properly setup ssh thing.
