The RV042 is the entry-level member of Linksys' line of wired business-class VPN routers. Linksys has three models in this lineup: the RV042, RV082, and RV016. All three are VPN and Dual WAN capable routers, with the main differences being the number of available LAN/WAN ports and VPN tunnels.
The RV042 has four 100 Mbps LAN ports and two 100 Mbps WAN ports on the rear of the unit. We reviewed the RV082 here in 2004, with its eight 100 Mbps LAN ports and two 100 Mbps WAN ports, all on the front of the unit. The largest model in this lineup is the RV016, with a total of 16 physical ports in front. The RV016 is interesting in that two ports are WAN, one is a DMZ, and of the remaining 13, eight are LAN, while five are configurable as WAN or LAN ports.
