However they never look at the contents / payload of the packet - only the context in which it exists. The other side of the coin is content processing - this is where the payload of the ip packet is examined - IMO a combination of content and context processing is best as these two techniques cmplement each other. bye rudi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
