Other New Features
As noted earlier, DSM 2.2 brings many new features to all of Synology's NASes. One that iPhone / iTouch users may like are the free apps that work with Synology's Photo and Audio Station features (described in the DS508 review).
All you need to do is enable the Photo and / or Audio Station features in the NAS, then download the free apps from iTunes (links here).

Unfortunately, I sent my iPod Touch away for battery replacement just before starting this review. So I couldn't check out the apps myself. But Synology provided this app screenshots shown in Figures 11 and 12.

You can check out the the DS audio app by downloading it and entering www.synologyamerica.com:15000 and you should be connected. The DS photo app can't be demo'd, however, since it requires read/write access that has been disabled on the demo server.
Updated 10/7/2009: Synology said you might need to log into the demo machine. Use admin for username and password if you get a login challenge.
Among the long list of new features, the following caught my eye:
Media Server improvements
The media server is now DLNA certified and should work better with your PS3, Xbox 360 or other media player that requires a UPnP AV / DLNA server. The iTunes server now also supports MOV, MP4 and M4V video formats and MP3 and M4A metadata indexing.
Two features have been added to help protect Synology NASes from network exploits when they're directly exposed to the Internet or large corporate LANs.
The Firewall feature (Figure 13) lets you control access to up to 100 services running on the NAS. You can use a pick list of pre-defined services, or specify your own. Rules can be drag-and-dropped to change priority order and each service rule can be set to allow or deny. So by using allow rules, you could tighten down access pretty well.

Auto-Block (Figure 14) provides protection against doorknob-rattlers by automatically blocking access from IPs that have too many failed login attempts via SSH, Telnet, rsync, FTP, iPhone, File Station, and management UI.
