Ipsec ikev2 to iOS 9+ and Windows – but no certificates

[rrauenza]

I'd like to use v2 but without certificates – I think my iPhone denies the .mobileconfig because I already have an "MBM profile" from my company on the phone.

I've found lots of howto's and tutorials, but a lot of them assume v2 w/ certs or v1.  Or they give instructions based on an older pfsense.  I also have a dynamic ip on the server.

I think what I want to use is xauth -- an account and password, with a shared secret.

If its any help, this is my xml config so far...

Log file … Seems like the issue is in the bypass lan phase.
