sshing into computers behind a router

Hi All, I have two machines, sitting behind a D-Link router. Both are
running Mandrake Linux 9.0 and I would like to be able to ssh into both
machines from the outside world. I have set the router to forward anything
going to port 22 but I cannot seem to do anything. I have tried to give
the computers names, thing1 and thing2 and try to ssh like:

ssh (E-Mail Removed)

and I get the following error:

host/servname not known

Any help would be greatly appreciated

To be able do address your machines by name you would need to have a
domain registered or use a service like dyndns.org or similar. Otherwise
you can access your machines only by the IP address of your router. And
you can access only one of the machines on port 22 because you can forward
port 22 of the router only to one internal machine.

What You can do is to redirect ssh traffic to one (and only one) of Your
inside machines and acces that one from the outside. If You then need to
access the other one, You can ssh from Your first into that second box.

My personal reading of the string "MicroSoft" expands to "NanoWeak"...

For the second machine you could forward a different port to port 22
on the second machine, if supported by the router or have sshd listen
on a different port on the second machine.

Assuming the router is running NAT, i.e. your ISP only provides a
single IP address then you would ssh to the ip address of the router
on default ssh port for machine 1 and alternate port for machine 2.
