D-Link Unified Services Routers offer secure, high performance networking solutions to address the growing needs of businesses. The integrated high-speed IEEE 802.11n and 3G wireless technologies offer comparable performance to traditional wired networks, but with fewer limitations. Each router provides optimal network security with features such as Virtual Private Network (VPN) tunnels, IP
Security (IPSec), Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP), and Secure Sockets Layer (SSL). These routers empower your mobile workers with client less remote access anywhere and anytime using SSL VPN tunnels.
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-250N, DSR-500N and DSR-1000N are capable of simultaneously managing 5,10 or 20 Secure Sockets Layer (SSL) VPN tunnels respectively, 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-250N supports up to 25 simultaneous VPN tunnels, the DSR-500N supports up to 35 simultaneous VPN tunnels, and the DSR-1000N up to 70 VPN tunnels.
