I have a similar but a more complicated situation. I have to connect to
a remote machine hidden behind two gateway machines. Is this possible
using multi-hop?

To illustrate with examples if the publicly accessible machine is
publichost, the internal gateway is intgw and the machine I want to
connect to is remotehost behind intgw, how do I achieve this with tramp?

I tried to set tramp-default-proxies-alist to something like this:

(("remotehost.\+" nil "/ssh:publichost:ssh:intgw:"))

But this doesn't seem to do anything. Any ideas?

PS: I use "remotehost.\+" because there are a number of remote machines
    behind the internal gateway machine with a common leading part of the
    name (e.g. remotehost1, remotehost2, ...)
