Hi, I am using a router with dd-wrt and openvpn over SSL or SSH and each time I was downloading something it would be really slow. For example, downloading the latest ubuntu 14.04 which is around 1Gb would take -- 4 hours if I double connect, meaning my router is connected to 1 airvpn router and my computer to another one -- 2 hours if I only connect to airvpn IPs through my router I fixed this by going to the dd-wrt interface, tab NAT/QoS, sub-tab QoS and select "start QoS": enable, Services priority : select "ssh", click "add" and then select "maximum" And then whatever mode of connection I would choose, my download speed for the same 1Gb file would be "13 minutes"!!! Look at the image I enclose. If this is not a good idea in terms of security, let me know, because I am not an expert on network settings, thanks.
