That would be John Mayes. The PIX was an outgrowth of Cisco's purchase of
a company called Network Address Translation (translation.com back in the
day). Frankly, the trend towards NAT and the need for some level of security
that was evolving in that day made most of those things inevitable.

Were there better approaches, perhaps. However, even with the PIX in place,
I think that Micr0$0ft did more to make http-based tunneling a widespread and
common phenomenon. It may have been pragmatic from their perspective, but,
it was also damaging to the internet and they were the ones that chose to be
pragmatic like that on a wide scale.
