i didn't read the original post (or re-posts thereafter, as i have
nothing of value to add to a bridging question), but i can add this to #2
there...in the case of REDIRECT--the client is expecting a response from
the target web server--so a SNAT doesn't make sense in that scenario,
as it would be pretty much guaranteed to break the communication.
REDIRECT is a whole different beast from DNAT.
