Do I understand you correctly? The web server (behind the corporate
firewall) should broker an ssh connection to an ssh server (also behind
said corporate firewall), then modify the same corporate firewall to allow
connections from some outside IP?

- How is the web server supposed to modify the firewall if you don't have
control over the firewall?
- Why do you want to add another point of failure?
- Do you think that it is a wise (ie. secure) decision to authenticate on
a web server rather than using ssh's authentication methods (preferably
public key only to non-root account) directly?
- If the corporate security policy doesn't allow remote access via ssh
directly, do you think the company will be happy to find out that you are
circumventing their policy?
