Small businesses looking for a router with advanced internet sharing capabilities need to look no further than the Linksys 4 Port vpn Router. Use the 2 internet ports as a failover or the let the router work as a load balancer giving your office maximum bandwidth efficiency. The Virtual Private Network (VPN) capability creates encrypted "tunnels" through the Internet, allowing up to 30 remote office or traveling users to securely connect into your office network from off-site. Users connecting through a VPN tunnel are attached to your company's network, with secure access to files, e-mail, and your intranet -- just as if they were in the building. You can also use the VPN capability to allow users on your small office network to securely connect out to a corporate network. The 10/100 4-Port VPN Router can serve as a DHCP Server, and has a powerful SPI firewall to protect your PCs against intruders and most known Internet attacks. It can be configured to filter internal users' access to the Internet, and has IP address filtering so you can specify exactly who has access to your network. Configuration is a snap with the web browser-based configuration utility.
