Why is there only one WAN Interface in the Port forwarding page?
Please check your WAN interface settings, the WAN interface should have the NAT feature enabled in order to appear in the Port forwarding configuration page.
In the figure below, you can find there are two WAN interfaces for you to select. If there is a WAN interface that does not show up, the reason is that NAT is not enabled on this WAN interface.
