The authby=null setting is not allowed in FIPS mode. FIPS requires
proper authentication of peers before it is allowed to send any
You should probably use the certificate based OE/mesh setup, eg:
In such a setup, each node has its own certificate and all nodes share
the same trusted root certificate CA. So you can still add nodes to
the mesh without reconfiguring all other nodes, since existing nodes
and new nodes all share the same root of trust via their certificates.
Note that FIPS does not allow negotiationshunt=pass. That is, during the
IKE negotiation, it is not possible to "leak" the traffic until the
IPsec tunnel comes up. That can only be done in non-FIPS mode.
