I'm calling this OT because it isn't a Linux question, but it is a 
computer question and there are some unixy elements to it.
I cannot connect to the PC via VNC, but I also cannot ping it.  On the 
other hand, traceroute from outside the network finds it OK.  On the PC I 
see this kind of info from ipconfig /all:

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).  Ping works to 
"localhost" or to 192.168.1.100 but not to 192.168.1.1 nor to 
CPE-24-94-198-51.mn.res.rr.com.
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
