Well, that is actually the problem. The custom rule only allows you to select ports in Protocol 6 (TCP) and Protocol 17 (UDP). IPSec uses Protocol 50 (ESP) and Protocol 51 (AH).
Here is a nice summary:

I saw the dropdown had a pre-defined rule for PPTP, which can be config'd using the custom rules. If the custom rules won't allow you to configure IPsec, it would be nice if it was included in the pre-defined dropdown.

Of course, you are correct. (I now have a Dunce Cap for every day of the week!) Looks like you are stuck with either PPTP on the RAS or OpenVPN (on the Orbi itself). I have been very happy with OpenVPN on my Orbi.
Perhaps you could hack at the iptables. I know that Voxel's custom firmware for the RBR50 allows customizing iptables. (I am also happy with this firmware. Probably fat and dumb as well.)
