XDMCP Problem (must be connected to internet)

[Tim Kelly]

First of all I must correct my original message. I can get remote X clients,
running on my Linux box to appear on my W2K box providing that my Dial Up
Networking is connected to the internet. If I disconnect then the X-Client
disappears off my screen. I now believe that this has something to do with
the dynamic IP address that my ISP gives me when I connect. I think that the
X-Client on my Linux box is using my dynamically allocated IP from my ISP to
communicate with my W2K box. It is not using the 192.168.X.X one. This
explains why I need to be connected to the internet for xwin to work.

I tried this experiment:

If I type:     xwin -query 192.168.0.2 -from 192.168.0.1  it doesn't work
However:   xwin -query 192.168.0.2 -from <MY DHCP>.<INTERNET>.<IP>.<ADDRESS>
then it works.

This confirms to me that LAN network addresses do not work for some reason.
I thought maybe this has something to do with firewall settings, but I don't
think iptables is even compiled into my debian kernel.

This might be a good time to let people know that my W2K box is setup for
Internet Connection Sharing (The linux box uses 192.168.0.1 as it's gateway
to the internet).

Anyone have any ideas!
