    inline tap mode ensure best performance and speed , by allow the firewall to pass the traffic and send a copy from the traffic to the IPS engine and if there is an attack the prevention action will be ignore !!!!!


    My question here what is the use of this mode if attack will pass , it will be like a stupid engineer who admire fast processing and the network is under attack ???

    Hi AhmedMohamed


    The purpose of inline-tap is detection of attacks while not compromising on performance. Use case scenarios for this is during initial deployment to assess integrity of the network before implementing integrated mode on the traffic path most susceptible to attacks. 


    Moreover you can still reset a TCP connection in inline-tap mode but not until the inspection engine returns a value. 


    Also, starting with 15.1X49-D10 inline-tap mode is not supported on SRX Series devices.


    Hope this helps
