Hi have you tested BolehVPN with RapidShare? I'm also experiencing the same issue you had with Streamyx where they've started to cap only the Rapidshare download. Reading from forums, TM applys a URL filtering, and if my http links has rapidshare in it, the download speed will be very fast initially, but if the download maintains for more than 15 seconds, the download speed just taper down to 1 kb/s. This applied even though i'm a Premium RapidShare account holder.
Also, I use Synology NAS to do all my downloads. Gathering from what I've read so far, I think I'll need to the below
1. Install OpenVPN into the NAS box
2. Apply the configuration file from BolehVPN.
3. Start-up the OpenVPN client initiating the connection to BolehVPN
4. Within the Download Manager, point the proxy to BolehVPN's website.
5. Check download speed.
Can the SME from BolehVPN validate if the above works?
