Pass-through authentication of IP-IP and GRE tunnel traffic in TAP mode

Devices perform pass-through authentication of IP-IP and GRE tunnel traffic when in TAP mode. To use TAP mode, connect the device to the mirror port of the connected switch, which provides a copy of the traffic traversing the switch. In TAP mode, the device processes incoming traffic from the TAP interface and generates a security log or report containing with information about threats detected, application usage, and user details.
