FileSharing on the Internet

Hello all,

Somethings been bugging me for a while now so I thought I'd ask the
question.

Scenario...

I've got a Origo DSL router with only one PC on the network. Router
is set to DMZ to my pc (192.168.0.1) so all ports should be forwarded
to my PC. Pc has firewall running

If I disable my firewall go to shields up and check my file sharing,
Sheilds up comes in on port 139 and shows my shares as exopected.

But If I go to my friends PC and try to see my shares with the
firewall disabled I get Network Path Not Found with only Packets from
port 80 registering on my PC?

So my question is, why is Shields up coming in ok and not another PC
on the internet.

If I try \\my fiends IP address I see his shares when he disables his
firewall but when he does the same to me he gets Network path not
found. Doesn't make sense.

PLEASE NOTE:

I am fully aware of the implications of allowing port 139 open on the
Net.

Strangely I have been trying exactly the same though for some reason
my Ports 137 to 139 still show as 'stealth' even though I have checked
all my settings and appear to have enabled sharing of NetBeui.

I don't fully unserstand this but I know my router has a default
setting of blocking outgoing requests from ports 137-139 going to the
DNS ports.

It ** might ** be something to do with the NAT router because even
though you are in the DMZ it is still the router or modem that has the
dynamic IP address and your computer has a different one so you are
being NATed, is that a real word :-)))

Why not just run an FTP server?
