I'm connected to internet using proxy server at other location. The other computer don't allow pinging. Also the DNS is not set, so the pinging of master.liveforspeed.net is not posible, (tracing) of 213.40.20.2 is possible but it gets stucked in local network (i'll fix that problem). BUT. The Mozilla, Thunderbird, IExplorer and all other windows programs allow using a proxy and they work fine, even now.
I have full access to other computer and program for proxy (ccproxy), but I don't know what to do in this case. Is it posible to use a proxy with LFS? I can't connect this computer in any other way to internet.
