I've set up the Linksys WRT54G to share the broadband connection directly from the modem to around 30 users or so in our organisation. I've used MAC filtering and and WPA-PSK encryption. I'm pretty new to all this stuff. I need a way to monitor how many users are logged on and hopefully see what they are accessing on the net to prevent abuse of the network. Is there a nice software solution for this? Better yet, is there a way I can link each user who is connected with their MAC address?
