Cannot ping through Fortiweb400E in transparent mode

Hey, I'm new to Fortinet in general.

We just got a fortiweb 400E and Im basically trying to ping through it and cannot.  Im not sure why.

Basically what Im trying to do is this.....Laptop(192.168.1.1) >Cisco FW > Fortiweb400E > Cisco FW >laptop (192.168.1.10)

The Ciscos are in transparent mode, I can ping through them no problem.  I'm guessing its a policy somewhere?  But I cannot see anything obvious in the logs.  I've turned on traffic logs and they tell me nothing.  I currently have it in OP mode "transparent inspection", port 1 is Mgmt on a different subnet, port 2 and 3 are plugged into each FW.  Any ideas would be great......
