Port forwarding doesn't give IPv4 option

I have the latest generation 3TB Tim Capsule. Using Airport Utility on my MacBook running El Capitan, if I add a port to forward the dialog that comes up shows "IPv6 Firewall Entry" and is grayed out. I'm trying to port forward port 3389 for a Windows PC that isn't using IPv6, but Airport utility won't let me changed it to IPv4 Firewall Entry instead of IPv6.

Is Apple requiring IPv6 now, or am I having some other issue? I may just enable IPv6 on the Windows PC if I have to, but I wanted to make sure I'm not crazy.

Sorry, cannot duplicate what you are reporting

Open AirPort Utility

Click on the Time Capsule picture

Click Edit in the smaller window that appears

Click the Network tab at the top of the next window

Click the + button under the Port Settings box to set up a new rule

A drop down box allows a choice of either IPv4 or IPv6 entries

Likewise, the setup on the iPhone or iPad version of AirPort Utility has the same options, with a bit different type of display.

That is the process I'm using. Here is what I am presented with.

Cannot duplicate. Try restart the Mac and AirPort device.

If no luck, then maybe another user can help.

I'm connected to the machine remotely right now. I'll try rebooting the Mac/Time Capsule when I get home.

You could have saved yourself some time if you had told us up front that you were not directly connected to the Time Capsule. 😉

The Mac I'm connected to is connected directly to the Time Capsule.

I see similar behavior when I access it from Windows using AirPort Utility 5.6.1.

The following documentation says there is a port mapping tab under advanced.

AirPort - Port Mapping Basics using AirPort Utility v5.x

I have an IPv6 firewall tab, but no port mapping tab. When I click to add an exception I see an identical dialog to the one on Mac, except there is no drop down box at all.

Also, rebooting the Time Capsule did not resolve.
