Indeed, from 19.3.5 (which I just checked) . . .
"The external IP addresses on the natd machine must be active and aliased
to the external interface."
I'm sure I read this section. Since that quote was right at the end, I'm
also sure I got lost before I got to that part . . . but since I checked
that section off my list, I probably never reread it.
Anyway, I took a stab at this a while ago, and sure enough, it fixed the problem.
"Your bad"? I beg to differ -- you're the guy who fixed this!!! And it's been
bugging me for weeks. Aaaaaaaaaaaaaaaahhhhhhhhhhhhhhhh!!!!!!!!!!!!!!!!!!!!!!!
Thanks so much Micheal.
