Bill,

Thanks, to you and a few others.

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.

Jeff
