Doug described the features found in Draytek routers pretty well in his 2910G review. Draytek also has an online demo of the 2130 series so you can browse through the screens yourself. You can also download the 233 page PDF User's Guide.
Here's a summary of the 2130n's general features:
- Gigabit WAN port with configurable speed, flow control, jumbo frames and power control
- Static, DHCP, PPPoE, and PPTP/L2TP WAN connection
- IPv6 WAN and LAN support
- Smart switch functions (described earlier)
- Hardware NAT acceleration (this is said to produce the very high routing speed)
- Dynamic DNS (dyndns.org, changeip.com, zoneedit.com, no-ip.com, freedns.afraid.org)
- Schedulable WAN, WLAN and VPN enable / disable
- IGMP snooping and status
- Support for USB 3G modem primary and failover WAN (supported modems)
- UPnP (including bandwidth limits)
- HTTP and HTTPs admin
- Telnet, SSH command line admin access (Linux root via Busybox)
- USB printer sharing
- USB drive sharing (FTP and SMB file sharing, FAT format only)
- Bandwidth monitor
- Web log view and syslog support
- Email alerts
- Software DMZ
- Port forwarding w/ optional local port setting
- Per port rate limiting
- Access / Deny access control w/ physical & logical ports, frame type, rate limiting and IP address
- Per IP (or IP range) session limits, up / down bandwidth limitings
- DoS attack Unicast, multicast, broadcast rate limiting
- Port rate and QoS control and port priority
- Single 2.4 GHz B/G/N radio
- Transmit power control
- WEP, WPA / WPA2 (PSK and RADIUS) wireless security
- WPS pushbutton and PIN
- Allow / Deny MAC address filter
- AP discovery (for finding clear channel)
and VPN features:
- 2 tunnels
- IPSec LAN to LAN, L2TP over IPSec and PPTP Remote Dial in
- Encryption : 3DES, AES
- Authentication : MD5, SHA-1
- IKE Authentication : Pre-shared Key
- Aggressive mode support
- VPN pass thru support
Despite this impressive feature list, there are a few key omissions on the wireless side. First, the product currently isn't Wi-Fi Certified, although Draytek says this is pending. Second, there is no WDS bridging repeating support and no router / AP mode switch (hardware or software).
More importantly, however, there is no way to control the wireless mode, which is set to Mixed (11b+11g+11n) and only 20 MHz bandwidth mode is supported. (Don't pay any attention to the drop-down selector for Wireless Mode in Figure 4—it doesn't have any other options.)

Draytek says the latter issue will be fixed via a "not too distant future" firmware update. But, vendors have made such promises before and not delivered. So if 40 MHz mode support is important to you, don't buy the product until the firmware fix is released.
Also note that the URL content filtering found on the 2910G is not implemented in the 2130n. That's no biggie, since you can always use the free filtering offered by OpenDNS.
Doug talked about Draytek's extensive bandwidth management features in the 2910G review. And in clicking through the various screens, I have to say the 2130n has probably the most extensive set of QoS features that I've seen in an off-the-shelf router.
Some of the features remind me of the magic shaper feature in m0n0wall, which would make sense, given the 2310n's Linux core. Figure 5 provides a taste of what you can get into if you need to set the priority for particular applications.

Fortunately, there are also simpler controls that let you limit the maximum number of sessions or set up and download bandwidth limits for single or ranges of IP addresses (Figure 6).
