	Thomas, you are right - thankyou. The output of "dmesg | grep
divert" shows that divert is disabled.
	kldstat also shows that the loadable module ipfw.ko is loaded which
suggests that that may
	be stopping ipfw being loaded in the main kernel (and therefore
divert sockets not being available -
	I read this in a post in the archives).  

	Does anyone know where to look to see where the loadable module
ipfw.ko may be getting loaded?  
	Is there a way I can grep for the pattern ipfw.ko from the /
directory so that it will look for a match on my entire file system? When I
use grep -r -i ipfw.ko /* |more   (to search my entire filesystem from the /
directory)
	I get the response grep: memory exhausted (I have 256MB RAM).
Thanks for any responses.

	Regards,
	J.S.
