Attack

[silenceti]

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 02:36:03 charon 03[ENC] header verification failed

I've received a lot of messages like this.

Can be an attack?

What can be done?

Thanks.
