A few things after determining the nic is not crapping out on you... Run a port scanner against your box. If you want to load something on the box itself, I suggest nmap. See if anything looks out of place. Keep an eye out for port 19 (chargen). I know of an old version of rootkit that would do things like shut off interfaces. I actually ran across this less than a year ago. It was a 6.0 Red Hat box that was a firewall for a really small town ISP. Pretty much put them out of business. Another thing to look into would be a traffic sniffer. I use ethereal when running X. Guessing that since this is a firewall you might not have X loaded try sniffit. You can find all of these at www.freshmeat.net. But before getting to paranoid (I'm always that way) I'd swap out the nics.
