That is a little bit tricky. First attempt would be

(add-to-list 'tramp-default-proxies-alist
             '("\\`protected\\'"
               "\\`kirk\\'"
               "/sudo:address@hidden:"))
(add-to-list 'tramp-default-proxies-alist
             '("\\`bastion\\'"
               "\\`kirk\\'"
               "/ssh:address@hidden:"))

But this would mean that every local route to root would go this
way. Here you could use the property of the su(do)? methods that they
don't care the hostname. The first rule could be rewritten as

(add-to-list 'tramp-default-proxies-alist
             '("\\`protected\\'"
               "\\`kirk\\'"
               "/sudo:address@hidden:"))

Then you simply need to open "/sudo:address@hidden:", and you are there.

Good idea. Maybe I'll write something like this for the FAQ. But not
before my holidays, which start on Saturday...

Best regards, Michael.
