So I need to secure the equipment we are using. I have read the manuals and can't seem to find that answers that I need. I first need to be able to shut down the NIC on the box. I would need to be able to turn this back on using the serial interface. (USB to Serial from another server) Because of this I need to be able to password protect the serial interface...ttys0. I have tried changing the rc.conf.local from firewall_type 'open' to 'closed' and that didn't not give me the desired affect of shutting down all IP traffic on the NIC. Now before anyone says why do you need to do that I work in the government IP space and they say I have to... I have not other reason.
Any help would be appreciated. I am pretty new to Linux ( I was a network engineer before I got thrown this project)
