I suspect this is almost certainly a routing table problem (on one or more of
the systems involved).
Quickest way to eliminate netfilter as a cause of the problem is:
iptables -A FORWARD -p icmp -j ACCEPT
as a temporary rule on whichever of the above machines are running netfilter.

90% of networking problems are routing problems.
9 of the remaining 10% are routing problems in the other direction.
The remaining 1% might be something else, but check the routing anyway.
