OpenVPN + Scrambled patch on Amazon EC2

view story

http://serverfault.com – Yesterday I deployed a regular OpenVPN installation on Debian Squeeze / Amazon EC2. The VPN server is in Singapore and I connect to it from China Mainland. Later on, after some tests I had to start thinking on patching OpenVPN with the "Scrambled" patch, to enable packet scrambling so I avoid the Great Firewall blocking my UPD packets. I compiled today from source said patch + OpenVPN, on a M3 Instance ( exactly as yesterday ) and now the connection is stable but I have terrible latency. yesterday I had 80ms when pinging the tun interface of the server and today I have an stable fat 270ms.
