Hi.
Actually I don’t used an IP range but a single IP address like this: 83.104.28.264 (for privacy I changed them). It is the exiting IP proxy server that our client can read checking on http://www.get-myip.com/. And it doesn’t work.
While with the IP machine, the one of single PC like 192.154.2.15, it does, but it means that I have to know the IP (or IP range) of all machines, while I know just the web server IP.
Thanks.
Enzo
