I have just got this working using an ASUS RT-AC86U running merlin 386.7_2, which is behind my ISP supplied router and thus NATed. The phone is a Samsung galaxy S20 plus, recently updated to android 13. Prior to (and post) the update I was successfully using VPN type "IPSec / Xauth PSK" per the asus doco. When looking at ikev2, I changed the VPN type but found the Xauth option was removed when I went to revert...There's a lesson in that :/

Random notes:
I have no real idea what I'm doing so take it with a grain of salt but it's connecting and has been up for an hour now. It seemed a bit slow initially but performance seems to have improved.

I messed around a lot with the config, some of which may or may not be necessary or secure or recommended.

Fortunately it is easy to identify randomized MAC addresses. 
There is a bit which gets set in the OUI portion of a MAC address to signify a randomized / locally administered address. 
The quick synopsis is look at the second character in a MAC address, 
if it is a 2, 6, A, or E it is a randomized address.
