Dual WAN 4-Port Gigabit Wireless AC VPN Router



The D-Link DSR Series Unified Services Routers provide secure, high-performance networking solutions to address the growing needs of small and medium businesses. The DSR-500AC has two Gigabit WAN ports offering load balancing and fault tolerance for the Internet connection. The integrated high speed 802.11ac wireless technology offers comparable performance to traditional wired networks, but with fewer limitations. The DSR-500AC router provides optimal network security via features such as Virtual Private Network (VPN) tunnels: PPTP, IPSec, L2TP, SSL, GRE, OpenVPN; supporting up to 95 tunnels. 

Comprehensive Management Capabilities

The DSR-500AC Unified Services Router has dual WAN Gigabit Ethernet ports to provide high availability for your WAN or Internet connections. Traffic can be load-balanced across the links with Outbound Load Balancing, increasing the performance and availability of business applications. The secondary WAN port can also be used to create a DMZ, isolating servers from your LAN.

Superior Wireless Performance

Designed to deliver superior wireless performance, the DSR-500AC has selectable dual band (2.4GHz or 5GHz) Wi-Fi connectivity, which offers the latest 802.11ac standard with Multiple In Multiple Out (MIMO) technology allowing to provide high data rates with minimal “dead spots” throughout the wireless coverage area. 

Complete and 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 series routers are capable of Secure Sockets Layer (SSL) VPN tunnels, as well as 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. OpenVPN allows mobile users to connect to the intranet via encrypted links with their PC, laptops or mobile devices. With purposely built hardware to accelerate VPN performance, the DSR-500AC can support up to 95 tunnels.

Web Authentication Capabilities

Captive Portal allows employees and guest users to be easily authenticated and authorized by accessing a customized landing page. Users can be authenticated by a local database, RADIUS, LDAP, Microsoft Windows Active Directory, NT Domain and POP3 server. A maximum of four servers can be configured at any one time.

Web Content Filtering

The DSR-500AC also provides a web content filtering feature to help administrators monitor, manage and control employees’ Internet usage. Static web content filtering helps to remove malicious objects such as Java applets, ActiveX, and cookies, or to block URLs by keyword. Dynamic web content filtering, which requires a subscription license, allows administrators to filter content from a list of categories. Multiple global index servers, with millions of URLs and real-time website data, enhance performance and maximize service availability.
