Hi Tom,
I think you are correct as far as where the rules came from, but I
don't think they are going to be grepable. The source contains
iptables.c, and a few other similarly named files. I haven't done C in
a while, but I'll try to make sure that is where my rules came from.
There are also changelog entries that appear to back this up as well.
I'll do a bit more digging, but I think I have my answer.
Thanks!
Craig
