XG V18 Port Forwarding different source and destination port

Question

Hi, 
 I would like to port forward with different source and destination port, i have created a service with different source and destination port but it doesn't seems to work, any ideas. 
 
 Scenario: 
 I have an application running on port 80 inside the network, i want an application to accessible through port 8181 from the external network using public ip.

Hi, 
 that will not work because the service will have been nat'ed at the source. You will need to change to 1:65535 for the external side. 8181 would the port the application will use on the users local network.

That is not a NAT, you are currently looking at. You only build a service definition. So how does the the App look right now. Most likely it looks like this: 
 1:65535 to 8181. 
 Then you create the NAT on Firewalls - NAT and translate it to your wanted port (I guess HTTP, but you can create a new service, looking like: 1:65535 to 80). Then you do the NAT in the NAT Table.
