Netgear has released firmware for more routers that support Live Parental Controls powered by OpenDNS.
Initial release
* Wireless-N 300 Router, WNR2000
Added 9/17/2009
* Wireless-N 150 Router, WNR1000
* Wireless-N 300 Router with DSL Modem, DGN2000
* RangeMax Wireless-N Gigabit Router, WNR3500 v2
(please note: it is important that the WNR3500 be a v2 model)
I will continue to update this list as more of the Wireless-N routers are released.
Information from my previous post:
There are some feature differences you should be aware of if switching to Live Parental Controls (LPC) from our core OpenDNS service:
* Using LPC eliminates the need for a dynamic IP update client using a new "Device ID". The router itself defines the network.
* Bypass accounts - allows you to associate a Windows computer with a sub-account that has different filtering settings than the default/all network users.
* Time based blocking - pretty self explanatory. This allows you to have different filtering rules based on local time
* All DNS queries from behind the router will be routed to the OpenDNS/LPC server even if the computer is explicitly set to use a different DNS server.
* LPC does not have statistics
* LPC will allow you to use your OpenDNS login but will not use any of the settings you currently have
* A separate dashboard has been created at
