Craig,
Pinging (and connecting to port 443 on) 96.86.86.53 work from amprgw.
Tcpdump on amprgw shows that IPIP traffic is being sent to you from
169.228.66.251. If you're not seeing it, either your modem or the
network are filtering it out. My bet is on the modem.

actually. The Comcast
business modem is in "transparent mode". This means that it is a L2 device
only. IP connectivity is handled by the SRX directly. I assigned my
Comcast Business static IP to GE-0/0/6 on the SRX.
I can run TCPDUMP on the firewall at the Unix command prompt which means
that I am seeing raw packets BEFORE the firewall rules are applied. Again,
no traffic at all from the 44 net side of the world.
