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.
This may be of interest:

The first traceroute is done using protocol 4 (IPIP) packets, the second
using UDP. Note that the IPIP packets are not getting to hop 17.
Hop 16 doesn't respond to traceroute probes, no matter what protocol
I use. I have no way of telling whether it is dropping IPIP or not.
The problem seems to be within a couple of hops to your end
of things.
