Thanks, Doug. You were right, I was missing the
gateway=YES
line in my /etc/sysconfig, but it didn't solve the problem just the
same. I turned off routed per your comment, and so far no success.
All the ip's are in my subnet. To be concrete, here is the netstat,
ifconfig, route, and ping results. If someone has the patience to
look at this, I'd appreciate any feedback.
m1 (205.179.170.68) is trying to connect to m3 (205.179.170.65) via m2

ok, i've removed that. actually, after enabling the middle machine
as a gateway, I tried it without, then started routed, and tried
again, to no avail.
