And you need to turn on packet forwarding on the box that is routing between subnets to do that.
Edit /etc/sysctl.conf changing ip_forward on:
net.ipv4.ip_forward = 1
Then apply the change with the following command:
sysctl -p
Also check that your iptables rules for the FORWARD chain in the filter table will ACCEPT the packets you want to allow between subnets.
