Product Description

Cisco 850 Series integrated services routers are fixed-configuration routers that support broadband cable and Asymmetric DSL (ADSL) over analog telephone lines connections in small offices. They provide the performance needed to run concurrent services, including firewall and encryption for VPNs and optional 802.11b/g for wireless networking. The Cisco Router and Security Device Manager (SDM) Web-based configuration tool simplifies setup and deployment, and centralized management capabilities give network managers visibility and control of router configurations at the remote site.

Main Features:

  • Secure connectivity with Stateful Inspection Firewall and IP Security (IPSec) VPN support for small offices
  • 4-port 10/100 switch
  • Secure WLAN 802.11b/g option with a single fixed antenna
  • Easy setup, deployment, and remote management capabilities through Web-based tools and Cisco IOS Software
  • Routing Information Protocol (RIPv1 and RIPv2)
  • Layer 2 Tunneling Protocol (L2TP)
  • Network Address Translation (NAT) and Port Address Translation (PAT)
  • RFC 1483/2684
