Hi Andrew,
Your email was very helpful. I just turned-off the
firewall security (set it to Low) and everything
worked fine now. I'm in a company network that has a
firewall for outside transactions so I really did not
need the medium firewall security for internal network
needs.
Thank you very much.

I think that "medium firewall security"
blocks X
traffic in that direction.
If you want "medium security" you should not
use xhost.
Consider xauth instead.
I find that ssh makes the xauth cookie
management transparent
and use it all the time instead of telnet.
