Question on LAN security?

[SDatl404]

I'm trying to secure my LAN and i'm not finding anything in this firmware. I'm trying to prevent un-authorized devices from plugging in to my network.

1 - Mac-filtering on the LAN.

2 - Shutting off un-used ports.

Anyone know how to achieve this with this firmware?

You can blacklist the devices that you don't want in Firewall -> Network Services Filter. I've never had to do that so I can't even begin to walk you through it.
