if the web server is apache, you could use mod_proxy to tunnel to the ssh server...
Make sure mod_proxy is turned on, and add the following to your httpd.conf
Code:
ProxyRequests On
AllowCONNECT 22
<Directory proxy:*>
Deny from all
</Directory>
<Directory proxy:127.0.0.1:22>
Allow from all
</Directory>
