I have an AX920 Router I got From OmniFiber and trying to setup IPSEC VPN to connect with my iPhone and iPad.  The fields in the VPN setup don't see to match the fields needed on the iPhone/iPad VPN setup.

For example: Account, Password.  These fields aren't in the 920 setup.

Also, how do I enable the VPN? I don't see any option to "enable" it just states the status as "Down".

I don't find any instructions in any of the manuals available, YT or the internet, which all seem to be very generic.
