Thx for your answer.
In my rc.conf file, I do have

Probably have to block in my firewall.
After reading your reply, I've done some more digging, and this is what

1 Redirect Datagram for the Host
2 Redirect Datagram for the Type of Service and Network
3 Redirect Datagram for the Type of Service and Host
