Thanks for picking this up with me. I did what you told me, and I am even more 
confused now. WHen I block the port 1720 on the NM box, and I try to telnet 
to it, I get the message

ben vaio:~$ telnet 1720
Trying remotehostsiphere..

ANd it hangs here, never connects. Now when I enable the 1720 port on the NM 
and I telnet to it from the GM, I get the following.

ben vaio:~$ 1720
Trying remotehostsiphere..
telnet: Unable to connect to remote host: Connection refused

What this might be? As I said, the NM has a router with DMZ enabled. I thought 
that the port 1720 might be disabled by the ISP by default, so I tried the 
same with 1721 but it came to be the same. Telnet test showed the same. What 
else should I try? It seems that the NM side is the problem obviously, as it 
rejects the telnet connectiuon even though the port is open to it. It is a 
Windows XP with SP2 and the firewall is set as I described above.

Thanks again
