What problem are you trying to solve?

As you seem to want to do, I login to certain machines from both inside 
and outside the office.


Mostly, I use a VPM so I always seem (to the office) to be on the 
inside, but for special occasions I have the exterior firewall direct 
ssh to my desktop where very few have an account. To clarify:

This goes to my desktop
ssh example.com
This goes to the server
ssh example.lan

After the first, I can get to all of .example.lan directly.

If I ssh in to there from outside, I then can ssh to other machines as 
me, or as root (according to taste, not all my machines allow this), and 
if as me then I use sudo if needed to do administrative things.

ps
You can also use xinetd as a redirector, so ssh to port 22 gets you to 
one system, ssh to port 23 to another. Port 5000 isn't a good port to 
use, it's used (unofficially) by other packages.
