Hi Chris,

> Is that option maybe obsolete with IKEv2? Afterall, pfsgroup is listed under "Removed parameters (since 5.0.0)":

DH groups for IPsec SAs are configured differently for IKEv2 and since
5.0.0 also for IKEv1.  They are added to ESP/AH proposals (esp/ah
setting in ipsec.conf).  If you currently don't have any configured then
use `none` on Windows.  However, if you want to use a separate DH
exchange when rekeying CHILD_SAs then configure a matching DH group on
both ends.
