Sounds like you're missing a route to 172.16.1.0/24 (or whatever the
subnet is) in your local PC attached to eth0 and you're missing a
route to 10.0.0.0/8 (or whatever the subnet is) in your 172.16.1.54
host.

As I understand your question, I think the missing routes should be in
the firewall router.  If it is a hardware router, it should already
include routes for the connected networks.  So I suspect that it's
another host that you intend to act as a router.  Perhaps you didn't
start any routing protocol in that host.  In the old days, that was
in.routed but I don't know what it is these days.

Does each host know a default route to the firewall?  You display
routes with:

    netstat -nr
