USG Flex 100W Port Forwarding Video?

I used to port forward with my old USG but it appears a lot has changed over the years.  I thought I had covered all of the steps to forward a port but I've missed something somewhere.  I see that there are some videos of how to PF with the older USGs but I can't find one for the Flex Series. 

Is Zyxel planning on a video or steps on port forwarding?

Thanks for the help!  Love the Flex and the ability for Geo Blocking!!
