It looks like that 10.0.0.2 does not have a route to 192.168.0.0/24 or
that 192.168.0.2 does not have a route to 10.0.0.0/24 or both:
192.168.0.2# ip route add 10.0.0.0/24 via 192.168.0.1
10.0.0.2# ip route add 192.168.0.0/24 via 10.0.0.1

If the firewall is the main router for the network then you can set up a
default route to it on each of the other hosts:
192.168.0.2# ip route add default via 192.168.0.1
10.0.0.2# ip route add default via 10.0.0.1

You will need to have the iproute package installed to get the ip(8)
command.
