After reading http://www.howtoforge.com/forums/showthread.php?t=2387
I'm one step closer ...
In the file "hosts" of my client-PC I've written
10.30.50.135 web1.lel www.web1.lel
When I now type www.web1.lel
in the adressfield of my browser, I access to the server, but the message:
"this IP address comes is several times used. In order to reach the desired Website, you give their Domain in place of the IP address in the address line of the Browsers "
What's going wrong ?
