Hey!
I have a linksys router and i want to block certain aspect of the internet from 1 specific computer. For example, how do I block MSN on computer #2? (i know the IP address for all my computers and I have strict access to the router so anything goes.

Any ideas on how to do this? like how do I know which setting to block and all that?

edit: I know it may sound simple but blocking 1 computer seems to block my computer as well. is this a glitch in the router or am I doing it wrong?

Not sure that the firmware on the Linksys router can actually block specific ports for specific IP addresses. You may need to look at something like DD-WRT to install as your firmware on the Linksys. It provides a LOT more functionality.

Tomato is another. Very nice, very flexible. My favorite alternative firmware.

MoB: If you click on the link that cyrnel posted, there is a flash video called Access Restriction that shows you exactly how to block stuff to certain inside IP addresses using Tomato. I've never used it before, but cyrnel usually seems to know what he's talking about, so quite a viable alternative you would have.

I know with the dd-wrt you can block certain protocols from certain computers at certain times

mexican, most Linksys routers these days, wireless and wired, allow for some basicc firewalling rules. Just add a block rule for that IP and that port, inbound and outbound.

Thanks bendsley. So long as "usually" means half the time and SWAG the rest.

Tomato is damn nice compared to the others in many ways. Shaping, captive portal, freeradius, rrd and graphing, additional packages, easy for new users, etc. The only time I install big stuff now is for failover/CARP, or just for heavy traffic/filtering/vpn needs. Buffalo's hardware is about as far as these things scale. Then it's time for pfSense on CF in an old box.

Amazing what can be done on $50 hardware or on junk from the closet.

To the original question, yes, you can block in just about any way imaginable with several of these alternates. For Tomato you get scheduled wireless, specific sites, traffic types, for specific MAC/IP addresses, combinations, all with very flexible schedules, etc.

Oh, and it's much more stable than factory firmware. Try it. You won't go back.
