I have qos in 4 router cisco  connected by metroethernet, and i have one firewall connected in the same metroethernet.

The config in router cisco is:

policy-map QoS
class Trafico-Voz-Out
  priority 1000
  set cos 5
class Signaling-Voz-Out
  bandwidth 96
  set cos 3
class class-default
policy-map QoS-Metro
class class-default
  shape average 6000000
  service-policy QoS

I can implementate QOS in firewall fortigate, and work without problem, or i  need install another router beteween router and firewall, and connected the router direct to metroethernet with qos. What you recommend?.

You probably need to assess how much traffic will be going through the firewall performance of your firewall, i presume your firewall will be performing NAT/ACL/Packet-Filtering (Layer3-4) is it acting as an application gateway as well? and implementing QoS on the firewall might just overkill. If your firewall is capable of QoS and is a high performing device should be fine to implement QoS on your firewall itself.
