Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-security@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org My apologies if this shouldn't be posted to this group, but I didn't know of any other place where an open discussion among "friends" could take place. If I should take this elsewhere, just let me know. Is it possible to encrypt ethernet packets so that all layers above layer 2 would be encrypted? The idea I had was to make a device that could defeat a TCP sniffer by encrypting the IP headers. Is this doable? Viable? A reinvention of the wheel?
