    DNS Server/PortScans


    I have syslog on router set to forward messages to my Home Server which is also functioning as a DNS Server. Whenever the router gets portscanned or drops an incoming packet I get a message in syslog on my DNS Server saying "client 127.0.0.1#33306: view xxxxxxxxxx: RFC 1918 response from Internet for xxx.xxx.xxx.xxx.in-addr.arpa" the xxx.xxx.xx address is the IP of my router.

    Is this normal, how can I protect or change this?
    I'm pretty confused here, because from what I've read about RFC1918 it has to do with trying to query private Ip ranges, but I'm not exactly sure in what regards it has to do with.

    Yes, I have seen that, am using the RFC1918 zones, but I still get that message whenever my firewall drops a packet. Thanks

    the xxx.xxx.xxx.xxx is that the internal interface IP on your router or external?
