Hi, I have a residential client with a NG100 in test.
I noticed an abnormal quantity of anti-spoofing messages in the security log.

Anti-spoofing: Packet from LAN Switch, proto:TCP, len:52, ->, flags:[ FIN ACK ], seq:3089641063 ack:209339365, win:2047, tcplen:0

None of these ip addresses is related to my client.

The network consists only of a couple of Mac and a 4 iPhone, plus a PS4.
Any idea on what could be causing this ?
None of my other KC have any anti-spoofing message in the log.
thank you
