Speedtest.net fails when routing traffic through squid proxy
I have been playing around with the Squid package for the latest PFSense release, and right now I am encountering a problem where the speedtest.net (beta.speedtest.net) fails to launch when I route traffic from a host through the proxy server. I've read elsewhere that the ICMP helper option can sometimes cause this but I have it disabled and the tests continue to fail.
Any ideas on where I can look/what I can try to get this working?
Thanks in advance for any suggestions!
