When I started the system today, I found that again it had no 
connectivity. I did some checks and then found that 'natd' was not 
running. But this is not happening that frequently, and seems to only 
have started after the last system update. Could be some sort of race 
condition. Is there a logfile that natd writes to, so that I may 
investigate the reason why it is exiting?
