i have squid proxy server setup on a ubuntu machine - i am just learning at the moment so trying out things..
i have configured my firefox to run thru the proxy. its all working well
i went to www.whatismyip.com - came up with proxy server ip - so far so good
then i go to www.speedtest.net - they display my original IP address.? how is that possible? thru the ping test they do right at the start? and they get information off that some how?
i can see that proxy server is working, because when i test my speed thru firefox configured with my proxy the pings are much higher and speed is much lower.
when i run a speed test thru IE which is not proxy configured i am getting far better speeds. so proxy is working fine.
