If you use telnet without a specific port, it will use port 23 
(telnet).  You could connect to a Web server on the standard port by using 
port 80, or to your MTA by using port 25 (SMTP).

I don't remember the first part of this thread, but if you are behind a 
firewall at work (which seems to be the case), and the sysadmin follows 
SOPs, then all ports are blocked unless he specifically allows them.  In 
that case it makes no difference if you set Apache for port 80 or port 
8080.  Of course, having telnet and FTP ports open while blocking http 
would be unusual...

The bottom line is that you need to find out if the firewall is blocking 
traffic on port 80 incoming.  Can you connect to another Web server on a 
different campus computer (and not the official site, which might be behind 
a different firewall or in the DMZ)?
