Using DD-WRT for Work (by Tony Fortunato)




For those of you who aren't familar with DD-WRT, it can replace your home router firmware and provide much more control and additional features not normally available.

Some people I have spoken to dismiss it as a software hack for recreational use, but I have been using DD-WRT for work and find it very helpful for some jobs.  I use it in my lab, in the field, my wireless class, in my office and for some consulting engagments.

For example, some of the wireless features are;

  • create multiple SSID's with different authentication settings
  • configure each SSID with diffent QOS settings
  • monitor clients' radio stats (RSSI, NOISE, etc)
  • create a bridge, WDS or use the router as a client
  • can perform site survey to record what SSID's it can hear

Some other features;

  • I can monitor usage, number of TCP and UDP connections
  • can use Radius to Authenticate
  • QOS support
  • NTOP Statistics
  • VPN (Open, PPTP) client and server (with vpn version)
  • SSH Server and Client
  • Telnet server

and many other features.  In this tutorial, I show you how to get started by installing DD-WRT on a Linksys WRT54G home router.  Then I briefly show you some of the wireless features within DD-WRT.
