The packets are probably reaching the gateway but the gateway
doesn't have a route back to return the echo.  Either configure
RHS to NAT on eth0 so everything appears to come from
172.16.1.1 or add routes on the gateway forwarding your
private 172.x.x.x and 10.x.x.x subnets through 172.16.1.1.

A ping issued directly from DO will have a source address
of 10.0.0.2.  Only RMS knows how to return a packet back
to this address.  Add routes on the others to send 10.0.0.0/24
back through their RMS connection.

Your route tables could be a bit smaller if you remove
subnet routes that go to the same destination as the
default route but leaving them won't hurt anything.
