I have a home network consisting of several computers....I have a problem with my sister, who password protects her computer so that I can't see what she is doing on her computer.  I need to block her access to the network (and ultimately, the internet).  It is not a wireless connection, it is wired...and there are no options in the router to block access.  Any ideas?  I figured I could just make the usable IP addresses for our network in a different range than they are now, so as to block her access.  Any other ideas?  Thanks !!!

There probably aren't options in the router to block access, but there should be options in the router to only allow access from certain mac addresses.

See if you can find these in your router manual, if you aren't sure where to look, tell us the brand and model number of your router, and we will look it up for you.

you can't do nothing in there for blocking. your going to have to eather just unplug her computer or change it to a IP that will not work on your network like 192.168.55.1

Well my friend, I'm afraid I have some bad news. I could be wrong and I hope I am - but here is what I found out.
The router you bought does have mac address filtering, but only for wireless connections, not for hard wired connections. With that information I can tell you that the only way around her ability to get on-line is to physically pull the wire.

(I keep my router in my bedroom so I can do that with my kids.)


There are some things you can do to keep the kid off the net on the kid's computer, but kids have a tendency to either know how to get around that or friends who can figure it out for them. Software is never a 100 % fix.

The good news is a new router is only 20 - 40 bucks at wal mart, and despite what everyone who is L33T likes to think, name brands don't matter at all.

Would you like some recommendations?

only if she knows how..

looks like you could write a firewall policy to drop any packets incoming or outgoing..


Disabling lan access is a lot harder to do..  WIth out running some type of authentication server..   If if you assign her a static IP out of the DHCP range is it still going to work..   You are going to have to fudge the address or the subnet mask..

It is possible.. there are 4 levels of security on these routers.. 1-3 are pre-programmed and the user selects a level and the correct script is executed..

Level 4 is a custom configuration where you can write your own firewall rules.. http://www.westell.com/content/sales/327W.pdf  right around pg57..  So... you would have to write a rule that would disallow outbound and inbound access on * for your ip.. which still means that the ip address is going to need to be static..  I will try and find a guide tonight and write the rule if I can..

That is a good call.. I have the firewall rule written.. I am about 95% sure that it will work.. however, I am with cholla... More information on the situtation would be helpful before I post what I came up with..  You can either post it here or send a pm to one of the mods..

There are other ways of "figuring" out what she is doing without cutting her internet access..  While we may not go into all of that, as it is kind of a Gray area, cutting someones internet might not be the best thing to do.
