3. 2930n Features and Functions
Table 1: list of the Vigor 2930n’s most prominent or significant features.
| Draytek Figure 2930 Features | |
| Security | Stateful Packet Inspection (SPI) policy-based firewall; Website content filtering; DoS and DDoS protection, MAC address filters, IP address anti-spoofing, DMZ support, port-redirection, Open Port support. |
| Encryption | Hardware-based AES, DES, 3DES encryption; SHA-1, MD5 authentication |
| VPN protocols | IP Security (IPsec), Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP), L2TP over IPsec |
An integrated stateful packet inspection (SPI) firewall delivers policy-driven traffic controls alongside Denial of Service (DoS) and Distributed DoS (DDoS) protection. Content Security Management (CSM) complements these features for precise restrictions over network transmissions and payloads. The 2930n also controls use of instant messaging (IM) and peer-to-peer (P2P) programs and protocols. Moreover, the 2930n supports voice and streaming media, including Session Initiation Protocol (SIP), Real-Time Protocol (RTP) and Real-Time Control Protocol (RTCP) for VoIP and video conferencing.
Wireless Features
The wireless Vigor 2930n supports Wi-Fi approved 802.11n draft 2.0 wireless LAN, along with Multiple-In/Multiple-Out (MIMO) technology. MIMO lets this device use all three aerials simultaneously to transmit data on two antennas and receive data on all three (2T3R). Packet aggregation and channel bonding are available, with optional higher-gain and directional aerials sold separately. The 2930n also features a firmware-upgradeable Wireless Distribution System (WDS) for Wireless LAN (WLAN) bridging, Access Point (AP) discovery, automatic power management, wireless rate control and 802.11e Wi-Fi Multi-Media (WMM) support. We tested none of those features.
The 802.11n wireless protocol is called dual band because it works at both 2.4 and 5.0 GHz radio frequencies. The 802.11n protocol is backward-compatible with 802.11b and 802.11g, which operate only at 2.4 GHz, and permits faster 802.11n devices to occupy the higher band. On the 2930n, an active client list compartmentalizes the WLAN from virtual LAN (VLAN) groups and Ethernet interfaces to boost security.
This router also supports 64- and 128-bit Wireless Equivalent Privacy (WEP), plus personal and enterprise Wireless Protected Access in both WPA and WPA2 versions. The Vigor 2930 uses a hidden service set identifier (SSID), supports MAC address-based access controls and even integrates with 802.1x RADIUS authentication (unlikely in SOHO situations).

Where's table 2?
What file transfer speeds are achieved?
the Vigor 2820 achieves only half of the 2930's throughput - I think this should be stressed in the final comment!!!
