Choose a port to run the server on (usually 80)
Then tell your router to forward incoming connections on that port to the machine running the server .
Give the other guy the IP of the router and the port number the server is on .

Besides , I tried AnalogX servers , they are that simple .
They are designed to be simple .
Did you bother to read the help files ? (Duh , but did you ?)
Forget WAR FTPD , it's much more complicated then then the AnalogX servers .

Also , don't forget to put a file called index.html in the directory you set on the server .
Else the guy will get a big error .
Once your are done open your browser and type http://localhost:80 .
If you see the webpage you just made it's working .
For the second test :
Get your current IP from your router it's something like xxx.xxx.xxx.xxx .
Type : http:*****.xxx.xxx.xxx:80 .
If you see your webpage again , you did everything right and the other guy should be able to acces the webpage .
