I believed the problem with pinging from tunneled
hosts was
still there, but if it works for you, I must have forgotten.
It is a bit unclear what is going on. From a host that is exclusively on the IPIP
mesh the ping does not return (I see only the outgoing IPIP packet). From a host that is
both on the IPIP mesh and BGP-routed on internet it does work.
It looks like it replies "directly" (via the BGP route) to the replies sent as
IPIP.

Yes, that is what I believe is happening - the kernel is replying
to the decapsulated ping packet, and because the diversion of
outgoing packets does not (for some reason known only to the kernel
architects) occur, the reply doesn't get routed to the encapsulator
and is therefore not sent to the tunnel-only host.
Remember, the gateway is a FreeBSD system, not Linux. The kernel and
networking implementation is very different.

I'm only on the mesh here Rob and I can ping 44.0.0.1.
