Hello guys, I have a quick question for those of you in the know about network traffic. Here's the deal... There are 4 computers connected to a ROUTER, if for x reason one of them needs to be blocked from getting online what would be the best way to go about it? Common sense tells me to disable their ethernet card, etc... Instead of doing that perhaps a piece of software out there can do this without having to physically tinker around with the computer. Thanks, Adonis
Well there is a way in the settings..but if you dont need it on the network, you can just pull the plug. Either out of the back of the computer or the router.
Yes, that's the simple way... Anyone can walk back into my room and hook the cable back to the router and be back online in seconds. See, that's why I'd like something more sophisticated to do the job. Something that will prevent that specific computer from hoking up to the internet without having to mess with the computer itself. Thanks again, Adonis
OK I see, its more like a parental restriction thing. Let me check up on it and I'll respond back later. *EDIT Cant seem to remember! This is gonna bother me. Anyone else??
You didn't say what kind of router, but I believe most will have some kind of access control where an IP or MAC address can be blocked. All you would have to do is block them at the router, then unblock them if you later allow them to use it. The router configuration should be password protected so they couldn't get in to undo the changes. On a Cisco router you would create an access list, similar to access-list 1 deny x.x.x.x (where x.x.x.x is the IP you want to block) access-list 1 permit any (tell it to permit any other IP) Then apply it to whichever interface they come in on with an access-group statement - ip access-group 1 in. Home routers would probably have some access control through the web interface.
OK, I see... The router is a Linksys! And I do know how to work with it. I'll have to make their IP static and block it that way. Thanks, Adonis
Dont need a static IP. You can block the mac address of the nic instead. That way, if someone does change the ip to dhcp, it wont matter.
Go into your routers configuration (when you type in 192.168.2.1 or w/e you main I/P is) There should be an option to block MAC address, and you type it in and save it
Thanks, I appreciate it. Does each individual card have its own mac address, if so, can it be identified by simply running an IPCONFIG or would it be under LAN Connections and Properties? Thanks
Each card has its own mac. If you run ipconfig /all you will see it. The first 6 characters are the manufacturers ID. All cards from the same manufacturer will have the same set of chars. The last set of 6 chars is the unique id of the card. You will need the entire number for blocking it in the router.
