Hi

Yes, I disabled the SP2 firewall on the NM, and still no go. I dont have 
access to any other machines on the same network, so I cannot try to telnet 
into the box via 1720 from an internal machine, which would be something to 
try. And on top of all that, it is behind a Japanese router, which gives you 
the idea how easy it is to set it up, sepaking reading almost no Japanese at 
all. That is why I set the DMZ. DMZ is DMZ in all languages. Haha. Sorry to 
bother the list, I will try to contact the routers maker for further 
instructions.

Thanks
