This is our first Linksys review since fall of 2005 and we're happy to welcome them back. So with the niceties taken care of, let's dive into a look at the RVS4000. The 4-Port Gigabit Security Router with VPN is part of the company's "business series" product line. This line is aimed as small businesses who are ready to move beyond the consumer networking products available at their local retailer, but who are not quite ready to move up to Cisco "big iron".
The RVS4000 comes in an attractive silver and black squarish box that's 6-7" on a side. It has screw mounting slots on the bottom and indentations on the top to allow stacking of similarly-sized products. The front panel indicators are shown in Figure 1 and the rear panel connectors are found in Figure 2. Nothing out of the ordinary for either one.

Figure 3 provides a look at the 4000's board, which is based on a Star Semiconductor STR9202 Broadband Home Gateway Processor SoC. The product description says that the 9202 includes a "Layer-7 Content Inspection Engine, which is a powerful hardwire in-line signature matching accelerator". This engine apparently provides the 4000's IPS (Intrusion Prevention System) features.

The gigabit switch is safely hidden under a heatsink, which I didn't disturb. But a little sleuthing outed it as a Vitesse VSC7385. 64 MB of RAM and 8 MB of flash are the other major components.
