Site2Site Rules to route traffic through tunnel

Hello everyone

I have made a Site2Site VPN Tunnel and everything is ok, the tunnel is UP and stable. Now the problem is that i don't know how to route the traffic from Site1 to Site2 and the other way around. I know that i need some kind of rules. I have already made some Policy Rules and don't work.

My configuration is:

Site A Lan 10.11.0.0/16

Network VPN : 10.9.0.0/24

Site B Lan 192.168.1.0/24

Network VPN :10.8.0.0/24

Thanks in advance
