IPSec tunnel Incoming data problem

hey guys, I recently setup a IPSec tunnel between two offices. They both say they are up but theres only outgoing data on both firewalls, no incoming data which means I cant do things like ping and browse/connect to each office, even though the IPSec tunnel is UP. On each firewall, I created a static route for the other subnet to go out of the IPSec tunnel and I created policies so it allows internal to go out IPSec and IPSec to go to internal. Not sure what I' m missing... can anyone help me please? they are both fortigate 60c. thanks!
