Ban a specific Mac address?

[chillypacman]

Is there a way to get the DGN2000 router to ban a single computer (identified by its Mac address) from accessing the internet?

not by mac address ..yet you can reserver the IP for it's mac address and create block service

Another thing which you could consider would be to enable the 'Wireless Station Access List' found on the 'Wireless Settings' page. By specifying which MAC Addresses are allow to connect via WiFi, you would automatically block any others not given permission.
