Thx for your answer.
In my rc.conf file, I do have 
but I guess that's not enough.
Probably have to block in my firewall.

After reading your reply, I've done some more digging, and this is what 
I've found.

  5     Redirect                                 [RFC792]

            0  Redirect Datagram for the Network (or subnet)
            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
