I don't know if your cables are connected, but even if the interface is up, with no carrier, nothing will work. That being said, if you're not getting a carrier it can be that the ethernet autoselect didn't work, and you should manually put one in your hostname.if file.
You probably can't detect a misconfiguration using nmap or tcpdump. The best bet would be to try and login in your isp's equipment, and take a look at it. Specifically netmasks and routes. These things generally can be misconfigured. Cheers, -- Giancarlo Razzolini GPG: 4096R/77B981BC
