To be more precise, a PTR entry for 44.142.162.123 is needed in
order for AMPRGW (at UCSD) to respond to or route packets from
that address. This filtering is performed by the front-end
firewall in amprgw (ipfw on FreeBSD).

Hi Thomas
There's still no reverse lookup for
44.142.162.123 ; as discussed
before, until fixed, 44.0.0.1 will not respond.
Well, this is where I got confusing replies...
Some state I only need a PTR if this IP should be reachable from the
internet. So no need for a PTR for it to communicate with any other ip
within the 44.0.0.0/8 range.
Some, like you, state that a PTR is needed for any communication, even
within hamnet.
I tend to believe the first statement is the more correct one as this
makes more sense to me and filtering based on PTR is done at the
gateway @ UCSD and not on every hamnet router.
But I am in contact with Markus HB9CTB to look into the issue now.
