This is turning out to be interesting. After doing the usual tcpdump, netstat -rn and configuration checking I then unplugged the RJ45. Pulled it out of the server. Not connected. I then went to an independent ISP connection and could still ping the address. My theory is that the IP address has been hijacked by another. Called my cable service supplier and they agreed. So, I setup the FreeBSD box with another IP address - has been stable for 16 hours and put the old IP address on a laptop. Seems to be fine on the laptop - so far atleast. My ISP says that they have not as yet fixed the problem. No real 'for sure' conclusion.
