The Linksys BEFVP41 is an advanced Cable/DSL router with a 4-port 10/100 switch for sharing wired connectivity throughout a small household or business. It stands out against weaker models (BEFSR41/ BEFSR81) due to its heavy security features, such as DES/3DES encryption algorithms, MD5/SHA authentication algorithms, and IKE key management. Plus, the BEFVP41 can serve as a DHCP server for one’s network. Most notable about the VEFVP41 is its capability of a full IPSec Virtual Private Network (VPN), and its support for up to 50 simultaneous IPSec tunnels. Additional features of the Linksys BEFVP41 router include NAT, PPPoE, IP Filter, and MAC Filter support. The Linksys BEFVP41 retails for $119.99 and comes with a 1 year limited warranty.
