[strongSwan] Resolve plugin doesn't restore /etc/resolv.conf

With that command, usually only the CHILD_SA gets closed, but not the
IKE_SA. IP address, DNS configuration and other attributes are bound to
the lifetime of the IKE_SA in IKEv2, and not to the CHILD_SA.

Have you tried to terminate the connection with the --ike option?
