Robust VPN Features
A fully featured virtual private network (VPN) provides your mobile workers and branch offices with a secure link to your network. The DSR-150/150N, DSR-250/250N, DSR-500/500N are capable of simultaneously managing 1, 5 or 10, Secure Sockets Layer (SSL) VPN tunnels respectively, as well as 5, 10 or 15 Generic Routing Encapsulation (GRE) tunnels, empowering your mobile users by providing remote access to a central corporate database. Site-to-site VPN tunnels use IP Security (IPSec) Protocol, Point-to- Point Tunneling Protocol (PPTP), or Layer 2 Tunneling Protocol (L2TP) to facilitate branch office connectivity through encrypted virtual links. The DSR-150/150N simultaneously supports up to 10 IPSec VPN tunnels plus 10 additional PPTP/L2TP tunnels. The DSR- 250/250N and DSR-500/500N simultaneously support up to 25 and 35 IPSec VPN tunnels respectively, and 25 additional PPTP/L2TP tunnels.
Efficient Green Technology
As a responsible member of the global community, D-Link is devoted to providing eco-friendly products. D-Link Green Wi-Fi and D-Link Green Ethernet features save power and help cut energy costs. The D-Link Green WLAN Scheduler shuts down your wireless network automatically according to a schedule you define, allowing you to turn off your wireless network during off-peak hours, saving energy and keeping your network secure. The D-Link Green Ethernet feature can detect the length of the cables connected to the router and can adjust power usage accordingly to save energy automatically without sacrificing performance. It can also detect if a link is down on a port and automatically puts that port into a sleep mode, reducing the amount of power used. In addition, compliance with RoHS (Restriction of Hazardous Substances) and WEEE (Waste Electrical and Electronic Equipment) directives make D-Link Green certified devices an environmentally responsible choice.
