Not certain if this is correct ... but I might not be understanding what
you mean by two subnets.
I have up to found Linux boxes ... static 192.168.2.{10,11,12,13}
I have a Linksys WRT54GL (192.168.2.3) that 3 of the Linux boxes are
wired into. That WRT is connected to a larger net which eventually has
Verizon out to internet. I am localizing the tests to only run on two of
the Linux boxes which are wired into that WRT to minimize "points of
failure". I would consider my testbed to be a single subnet ... am I
mistaken?

Um ... yeah ... if I can learn enough in this beginning phase I know
that the word "properly do a full mail service" is potentially part of
my future ... but I'm putting blinders on until I can get a simple
telnet from one machine to another on the LAN.

FQDNs ???
There have been a couple requests for me to explain what and why I have
things the way I do and I am trying to get something written that makes
sense (and doesn't ramble)

What do I need to clear up?
Tim:
Appreciate the feedback and I am hoping I answered everything (sort of
the "what/why"). I think I've gotten it down to "I can make things
happen in iptables, but either not what I want or something else needs
to happen" -- posted latest results earlier tonight.
I do want to reiterate that your understanding of my using telnet is
right. My eventual target is mail, but telnet seems like a much easier
testing target to get the basics down in regard to learning what I need to.
