Re: Interesting infographic on the history of firewalls

I did something similar to this in 1994-5 at Harvard using a version of rot-13 and icmp.  Seriously.  And it worked.  :-)

When I was at TIS, in 199?2, I set up Onions' tunnel driver and a couple shell scripts that uuencoded the packets coming out of the tunnel, and emailed them to another system user with a .forward file that uudecoded the packets and injected them into a peer tunnel. With that setup, and its opposite on both machines, I was able to NFS mount filesystems across a secure mail guard. (Hint: if you're doing your own version of this, jigger the RPC retransmit timer in the NFS mount options, or you'll get packet storms that turn into email storms)
