I've run tcpdump on amprgw and can confirm that IPIP packets are being sent to you, including the RIP transmissions every 5 minutes.
I can ping your gateway on 110.175.89.41 from 169.228.34.84. If you are recording inbound traffic from it, you should see the pings from a few minutes ago. - Brian

I've now confirmed with my service provider that they are not blocking traffic either to or from amprgw. About 12 hours ago I started logging inbound ipip connections on my wan interface, but so far have seen nothing from 169.228.34.84.
