as Redimondo said, your pc behind the NAT must be the active part, means it must tell you, somehow, how it can be connected.
Then there're sevaral ways to do it.
But does your comapny policy allow this?

Question
connect to linux pc behind the NAT
Is there a way to setup a ssh connection to the pc located behind the NAT that I am not allowed to change the parameters of?
[ Outside -> Nat -> Linux:22 ]
I know it is possible to achieve through the port forwarding feature on NAT server, but I have no access to the NAT server.

if you want ssh, then you must have your home computer accesable from the internet, and turned on.
then in your computer in your school, issue:
ssh -fNR 2200:ip.on.your.school:22 yourusername@yourhomeipadd
you must have some name to know your computer in your school other than localhost. if you do not have one, edit /etc/hosts and add:
127.0.0.1 localhost yourschoollocalpc
and left it there.
then, from your Linux at home, issue:
ssh -p 2200 yourusername@yourschoolloc
and you will have a shell.
this is just an example. just check the help in ssh.
if the ssh connection goes down, then you must start it again. for that, you can setup a cronjob to check if it is still up, and if not, relaunch it again.
good luck. just don't do any illegal thing with this knowlege.
The command
"ssh -fNR 2200:ip.on.your.school:22 yourusername@yourhomeipadd
did not work.
If I enter it the way Redimido proposed to it gives me a syntax error. I modified it a little bit and I got "ssh -R port1:my.school.ip:22 -N user@ip" but it does not reply for ssh request from outside of a network.
P.S. There is a mandrake 7.2 (I think) installed in school and 9.0 at home. As for the version of ssh I havent had a chance to check that yet. I will try to upgrade it but it could be difficult to do that since it is an old version of linux installed there.
> the linux box behind the NAT must be the active part
Yes. I agree. What I am trying to figure out is how to achieve that.

only in a reverse way.
like VNC. you put your server sending requests to your external ip, and then in the external ip you launch the client, and they connect.
check this: www.tightvnc.org
vnc works that mode.
