Hi,

last month I installed a working (AFAIK;-) firewall using FreeBSD 4.4, ipfw 
and natd.

Sometimes I get a message:

> Nov 22 17:31:25 tor natd[456]: failed to write packet back (Permission 
> denied)
> Nov 22 17:31:58 tor last message repeated 6 times

There are approximately 30 packets per day causing this message.

I can't find a corresponding message in the ipfw-logs.

While my firewall continues to work, my former FreeBSD 3.x firewall stopped 
in this case from time to time.

Should I be worried? I hope there isn't a mistake in the ipfw rules..

Thanks for advice
Peter Ross
