Hi,
Have configured IKEv2 device as initiator to verify initial exchanges from
End-point to Security Gateway.
ipsec.conf has below parameters set:
type=tunnel left=2001:0db8:0001:0001::1 # Remote address
right=2001:0db8:000f:0001::1 # Authentication method leftauth=psk rightauth=psk
leftid=2001:0db8:0001:0001::1 rightid=2001:0db8:000f:0001::1 # Remote subnet
rightsubnet=2001:0db8:000f:0002::/64
Did you try adding 'leftsubnet=2001:0db8:000f:0001::1/128'?
Thomas,
With leftsubnet, IKE_SA_INIT request is not generated on the initiator.

IKE_SA_INIT exchange is successful and IKE_AUTH request is sent by the
end-point. Two traffic selectors are generated and the 2nd traffic selector has
the complete
IPv6 addresses as its range.

Why is it proposing ::/0 instead of 2001:db8:1:1::1/128?
