Then configuring an IPsec tunnel, I can usually set if the device should act as the initiator or the responder (or even both). However, what would happen if both endpoint are configured as the initiator and start the IKE negotiation at the same time? Will one of them switch to the responder role, or will the tunnel establishment fails?
More generally, should I always configure only one initiator and one responder or it does not matter if at least one device has the initiator role?
Thank you in advance.
