linux isue with static routing


Hello everyone,
I have this network simulated in virtualbox: network diagram

I am requested to make h1 and h2 communicate through R1.
I tried first to setup a static route on r1 (route add -host 192.168.2.2 gw 172.16.0.2)
I have also configured all of the ip adresses on every device.
after that static route, if i want to ping from r1 to h1 it does not work and it is trying to use the default route instead of the static route.
Can you tell me wat i have done wrong?
Thank you

A specific route will always take precedence over a more general route, so the host route should certainly have been chosen over the default route (which is the most non-specific route one can have).

For the host route on R1 to work, R1 must be able to reach 172.16.0.2 (R3), and R3 must not respond with an ICMP error. Can you ping 172.16.0.2 from R1? Is routing enabled on R3? Are there any firewall settings on R3 that might prevent packets from being forwarded?

I managed to make it work.
I forgot to activate ip_Forward.
Now it works.
Thank you
