When connected to my VPN server testing my internet speed with any speed testing website, such as speed.io, results in an upload rate of 0. When I connect to my vpn server with Cisco's AnyConnect, my upload rate is the real number. I use OpenConnect 5.99 with GnuTLS on Debian Wheezy. Browsing the web with OpenConnect works just fine. I have not been able to do any other testing beyond that. Any ideas what wrong here?
