I wrote a simple file server mainly to be able to send software updates to my
customers.

Evrything works fine. I am using TCP and the server is using port 12500.

The problem is that many customers have ports closed and simply refuse to open
12500. One answer is to tell my customers to go to router setting and open port
12500 which is not a very good idea. Router setting are confusing and even I have
diffuculties opening ports on some routers I've tested.

How should I tackle this problem? I tried ports 80 and 21 and it failed. How does
my FTP program get around this?
