An integer flag indicating whether this remote-access session's IKE negotiation is running over TCP rather than its normal UDP transport, a fallback Check Point supports for clients on networks that block UDP 500. This is the field an admin checks when a remote user on a restrictive network, such as hotel Wi-Fi, reports VPN connection failures; confirming IKE-over-TCP is active for that session validates the fallback kicked in, while it being off would suggest checking whether that fallback needs to be enabled for that user's profile. Example: a user connecting successfully only when raIkeOverTCP shows enabled for their session confirms their network path blocks standard UDP/500 IKE and they're relying on the TCP fallback.
