The Linksys BEFSR41 is a basic Cable/DSL router with a 4-port switch for sharing wired connectivity throughout a small household or business. Not only does the 4-port switch allow direct connections with PCs, but it can also in fact be ‘daisy-chained’ to other hubs and switches, therefore letting users implement it in a much larger network scheme. Most notable about the BEFSR41 is its advanced security management functions, such as port filtering, MAC address filtering, and also DMZ hosting. This gives the unit enough security to protect local computers from hacker attacks. Additional features of the Linksys BEFSR41 router include IPSEC & PPTP pass-through, QoS prioritization based on port or service type, and automatic detection of straight or cross-over cable. The Linksys BEFSR41 retails for $59.99 and comes with a 1 year limited warranty.
