Hoping to get a little help or insight on a port forwarding / opening problem with a Fortigate 600d

I have have a Fortigate 600D in my environment and it is working like a champ. I have a product that we will use to manage our visitors and it requires port TCP 5900 and UDP 161 to be open.

I have following the Fortigate Cookbook instructions to create a port forward and tried to open the port by creating a service and adding that to the IPv4 Policy. I am not able to get this to work and I would appreciate any help or insight anyone can give.
