Can anyone recommend a program that lists who is accessing the internet through a specific router? I have a Netgear WGR614 54 Mbps Wireless Router set up in my apartment, and I have a slight suspicion that someone living in the apartment next to me is accessing the internet through my connection. The connection is provided to us by the apartment, and they have a sort of quota system in place.
I don't exactly know what kind of program I'm looking for. I just need something that will either log who/what uses my router, or just reject anyone not on my network.
