Ok....

I have apache listening on port 80 local host. However when connected to the internet its is just as accessable to the world as any other web site I just have to access it through my IP address.

My SMTP server is also very much capable of sending email to any location in the world when I'm connected to the internet too. As is my FTP server.


If you don't believe me:

open up telnet when you are connected to the net:

connect to [clientIP_address] on port 80 and type "GET /" and see the page unfold in front of you.

Equally you could go to your favourite web browser and type in:
http://[clientIP_address]/index.htm into your adress bar.

Ask a friend in Africa connected to the internet to navigate to your IP and he will see what you see.
