The latest DSM release (DSM 4.0-2198) now fully supports UDP trackers
This will solve any and all problems you had with UDP trackers (although it is not mentioned in the release notes).
Just a word of advice for people who use the DSM for downloading torrents...
- Turn on DHT, set the port to the same as the BT port, apply the setting.
- Then, go back into the settings and disable DHT.
Why disable DHT? Well, DHT is great for finding additional seeders when trackers are down. That's where it works well. Where it is not so good is when you want to maintain your anonymity
DHT sends your IP and torrent hash out into the DHT ring, which quite simply allows you to be traced and logged far easier than with UDP trackers or encrypted peers.http://www.youhavedownloaded.com
uses DHT primarily to track downloaders, and software security firms use the same method to track you.
Also, DHT creates many UDP listening sessions on the DSM and could potentially bog down the CPU.
My advice is you should only enable DHT when you *really need it*.
