<br>
Can you even alter her laptop to redirect it's DNS?<br>
<br>
Assuming her computer sees your router as its primary gateway, you could set up an OpenDNS account (free), set the router to use that as it's DNS server, rather than the cable / dsl provider, then block the sites you don't want on your network. The number you can block is limited with the free account. I think you can do 50. This will block those sites all the time for everyone. If you wanted to allow access to some, you'd have to log into the control panel and turn them on.<br>
<br>
This will not require any changes to her computer. She'll be able to to bypass the block if she could A) change her dns settings, B) use a vpn, C) use a proxy, D) access web sites by IP address, sort of, or E) boot a Linux CD / USB stick which she has complete control over. OpenDNS will let you block categories of sites, including proxy's. It will catch about 90 - 95% of sites in that category. You can also block things like porn, etc.<br>
<br>
Some routers have parental control functions you can activate. Perhaps you could set them to only react to her MAC address and / or only at certain times.<br>
<br>
I have multiple wifi routers in my house for myself with throttled bandwidth (which I use when my wife is working at home), myself with unlimited bandwidth (which I use when she's not there), and my wife. You could have a router just for your daughter, and set limits on it however you want.<br>
<br>
If you have multiple routers, you can wire each of their WAN ports to the LAN ports of a master router, which then connects to your cable modem or dsl modem (through its WAN port). You can attach shared printers, etc., that everyone needs access to on the master router.<br>
<br>
Sincerely,<br>
<br>
