Product Overview

Overview (CISCO871W-G-A-K9)

Cisco 870 Series of integrated services routers are fixed-configuration routers that support multiple types of DSL technologies, broadband cable, and Metro Ethernet connections in small offices (Figures 1 and 2). They provide the performance needed to run concurrent services, including firewall, intrusion prevention, and encryption for VPNs; optional 802.11b/g for WLAN networking; and quality of service (QoS) features for optimizing voice and video applications. In addition, the Cisco Router and Security Device Manager (SDM) Web-based configuration tool simplifies setup and deployment (Figure 3), and centralized management capabilities give network managers visibility and control of the network configurations at the remote site.
Cisco 870 Series integrated services routers offer:

• High performance for broadband access in small offices

• Enhanced security, including:

– Stateful Inspection Firewall

– IP Security (IPSec) VPNs (Triple Data Encryption Standard [3DES] or Advanced Encryption Standard [AES])

– Intrusion prevention system (IPS)

– Antivirus support through Network Admission Control (NAC) and enforcement of secure access policies

• 4-port 10/100 managed switch with VLAN support

• Secure WLAN 802.11b/g option with use of multiple antennas

• Easy setup, deployment, and remote management capabilities through Web-based tools and Cisco IOS® Software

The little router that could

I use the router in a bit different situation from most people. I use it in a house where I have a web and mail server as well as my home network. Nothing really business or for profit.

This was my first attempt at learning about cisco IOS. This is definitely a capable tool for low throughput but high feature needs. I was able to set up routing, NAT, FW, IPS, and VPN capabilities. The advanced security IOS image makes a big difference. This completely replaces my Open BSD firewall doing with as good as or better features without the hassle of running a complete computer.

However, it does have it's down sides. First, the Java gui configuration tool is fairly junky. Don't plan on relying on it to do your configuring. About half the wizards ran, but the other half not only didn't run but gave no reason why. However, anything you can do in the wizard you can do in IOS it's self (as the wizards are just running IOS commands).

Second, the DMZ set up on this router is disappointing. As far as I can tell "DMZ", just means allowing a second VPN with some limited filtering. Personally, I was hoping to hang a dumb switch off the port and write some fairly complex rules, for my servers in the DMZ, however the router doesn't seem to want to let the external interface share the IP space of the DMZ. Maybe I'm miss-understanding what the IOS build allows and doesn't allow, but it's quirky enough I may just buy a separate cisco switch to put infront of the router which would host the DMZ servers as well as the appropriate ACLs.

Overall, this is a great router if you have either a small home or business you want to connect to the internet with the scale version of an enterprise solution as well as needing the full range of capabilities in a single package. I'd recommend it to anyone.
