What kind of IPSEC proposal is this?

    I don't know how to parse all that! My best guess is that there are 3 IKE: identifiers suggesting 3 configured proposals on the pfsense side but I have only 1 phase 1.

    Further, it looks like the hash algorithms don't match but I've tried a few and the HMAC_SHA2_256 doesn't change (at least that first one).  Am I looking in the right place? The examples in the pfsense IPSEC docs look nothing  like my configured proposals.

    Finally DH is set to Group 5 1536bit on both ends but the configured end is showing 3072?  Why?
