How to Setup a NAT Rule (Port Forwarding)

shopy95

I would like to know how to set up port forwarding for my QNAP NAS with the Zyxel USG Flex 200H. The menu at USG FLEX200 is slightly different from the old USG110

They should look about the same

Set Incoming Interface to your WAN named interface
Source IP any unless you want to allow from a given IP
External IP your WAN IP on interface
Internal IP to your NAS IP
ports to map 443 to 443 or have external to be different to Internal

NAT loopback if you want to go to your NAS by WAN IP
