I know this has to be a FAQ that has been asked a million times but 30 
minutes of searching did not get me an answer so I'm hoping one of you can 
direct me to the web page that explains this.

I installed Enterprise VNC server on my PC and had this problem.  Now I'm 
using Ultr "at" VNC server and having the same problem.  The problem is that I 
cannot connect to the PC.  I cannot ping it, but traceroute from outside 
the network finds it OK.  On the PC I see this kind of info:

When I SSH from the PC to a Solaris box outside of my home network, the 
Solaris box says I'm connecting from CPE-24-94-198-51.mn.res.rr.com (I 
changed that number just a bit, but you get the idea).  So I try to 
connect from outside my home network to CPE-24-94-198-51.mn.res.rr.com 
using http as follows:

http://CPE-24-94-198-51.mn.res.rr.com:5800

and I'm told "Connection was refused when attempting to contact ..."

So I am stuck.  I have Time-Warner cable modem and Linksys 54g wireless 
router (but I'm plugged into the router with an ethernet wire).  I'm 
running Windows XP x64 (but I doubt that has anything to do with it).

Thanks in advance for any tips.

Best,

Mike
