I've read through the guide on how to port forward on an Airport Extreme, which is what I own. When I log into the settings and click on the "Advanced" tab, there is no option for Port Mapping. I've entered "Port Mapping" in the search box and 2 options came up: "NAT > Enable Port Mapping Protocol" and "Port Mapping > Port Mapping" I have clicked on both and nothing happens. The Airport Extreme is bridged to a Siemens Gigaset SE567. Could this be the problem? If it is, is it fixable?
