No

Can't telnet to 177 either.

And tcpdump -i eth0 src port 177 shows no activity when I try...

So...I checked my router, and it shows port 177 traffic trying to 
connect to 192.168.0.1, the IP of my redhat 7 server, which I'm NOT 
trying to connect to.

So, I killed all the sessions in X-Win32 that I had configured, the 
redhat 7 session used at work, and the FC1 session I was trying to use 
at home. I then started up a 'tcpdump -i eth0 src 177 -nn' on a SSH 
terminal on FC1 and created a new X-Win32 session to try to connect to 
192.168.1.2.

This yields some expected activity:
# tcpdump -i eth0 src port 177 -nn
tcpdump: listening on eth0

which seems to be telling me that X-Win32 is *trying* to connect...
unfortunately, no xsession gets created :-(

Guess I have more playing around to do. Perhaps starnet's tech support 
can help.
