Attack



  • HI,

    Since the last upgrade (yesterday), i guess my pfsense is some kind of "under" attack.

    Checking logs:

    Jul 27 05:37:40 charon 05[NET] <6> received packet: from] (312 bytes)
    Jul 27 02:36:12 charon 03[NET] received invalid IKE header from  - ignored

    Jul 27 02:36:03 charon 03[NET] received invalid IKE header from - ignored
    Jul 27 02:36:03 charon 03[ENC] header verification failed

    I've received a lot of messages like this.

    Can be an attack?

    What can be done?

    Thanks.



  • Is it from the WAN interface logs??
