Greetings,
Responder: OpenBSD 6.8 GENERIC.MP#4 amd64 iked
Initiator: pfSense 2.4.5-RELEASE-p1 (arm) [FreeBSD 11.3-STABLE]
(built on Tue Jun 02 17:45:24 EDT 2020) strongSwan 5.8.4
Using IKEv2 for tunnel from a residential gateway to passive iked
responder. Using RSA auth with PKI from ikectl(8). Phase 1 setup with
IKE SAs and initial child SAs and connection time flow insertion works
great, but subsequent rekey attempts after configured timeout fail out
with NO_PROPOSAL_CHOSEN:

During the failure state the tunnel stays established and both sides
report connected status, but no traffic flows over the tunnel.
Attempts to renegotiate phase 2 appears to happen every 10s after that
point.
