An article in the December 31, 2009 USA Today reports an increase in the amount of cyber-robberies targeted at small businesses.  The article cites an example of a county government that was a victim of cyber crime for nearly $300,000 dollars. The county's bank faulted the county government as “the county's network did not have an effective firewall, its virus protection was woefully out of date and the county's treasurer did not follow internal controls that would have prevented the unauthorized transfers.”

The article illustrates that security threats to businesses and consumer networks from the Internet are growing, making it more important than ever to deploy solid network security devices such as firewalls, virus protection, and web filtering technology.

In this review, I'm going to look at the Draytek Vigor2910G Dual-WAN Security Router.  This router is equipped with a highly configurable firewall with the ability to filter Instant Messaging (IM), Peer-to-Peer (P2P), and Web traffic to help reduce the risk of network compromise such as the one cited in the USA Today article.

The 2910G is one of six models in Draytek's 2910G line, ranging from the 2910G to the2910VGi.  The “V” in the model name means the router has 2 FXS ports, the “G” in the model name means the router has wireless capability, and the “i” in the model name means the router has ISDN capability.  I'm going to cover the “G” model with wireless capability. 

Under the Covers

The router is enclosed in a basic plastic black case measuring 8.5”W x 6.25”D x 1”H.  The front of the device has indicator lights showing activity on the WAN and LAN ports, as well as a several other indicators providing status on enabled features. 

Feature indicator lights show when the DMZ functionality is enabled, when a QoS rule is enabled, when DoS protection (=”Attack”) is enabled, when the WLAN radio is enabled, and when a 3G USB card is active as shown below in Figure 1.

The rear of the device has (4) 10/100 LAN ports, (1) 10/100 WAN port, a USB port, power connector and on/off switch, as well as two upgradeable (RP-SMA connector) wireless antennas (Figure 2).  The power supply is a typical 100 - 240 V wall wart. I appreciate that the 2910G has an on/off switch.  To me, it just seems better turning a device off before unplugging it.

Taking a look at the board (Figure 3) reveals a Samsung S3C2510 32Bit ARM9 processor clocked at 166 MHz.  Additional components include a Micrel KSZ8995XA 10/100 switch, 16 MB of RAM and 4 MB of flash. The radio is a Gigabyte GN-WIAG02 mini PCI card using an Atheros AR2414A SoC Super-G radio.
