So, I think what's going on is that IPTables moves a packet from one
'bucket' to another, depending on the mangling happening.  So if your
packet needs to go from A to B to C to D to E states to get from your
input to your output, logically you're -i A and -o E, but no packet will
ever match -i A and -o E simultaneously - iptables is concerned with the
details, not the logical result.

This is pretty cool stuff. /me *makes evil plans*. :)
