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). - Brian

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.
