Airport Utility tells me my new/old Airport Extreme has a Double NAT setup, and needs to be switched to Bridge Mode. The only useful(?) information I can find online seems to relate to very old OS versions.
Someone please tell my how to switch to bridge mode. Thanks.
MacBook Pro with Retina display, macOS High Sierra (10.13.3), 16GB RAM
Open AirPort Utility on your Mac (Finder > Applications > Utilities > AirPort Utility)
Click on the picture of the AirPort Extreme
Click Edit in the smaller window that appears
Click the Network tab at the top of the next window
Change the setting for Router Mode from DHCP and NAT to "Off (Bridge Mode)"
Click Update at the lower right of the window and give the AirPort a full minute to restart
