Firewall tab in System Log reports ad infinitum

  • The title says it all; I have TONS of these:

    Apr 19 01:21:59 WAN UDP

    I'm not even using a 10 dot network range.  Can someone please tell me what these are and more importantly, how to get rid of them.

    Thank you,


  • You are a cable customer. Your ISP uses addresses in this range to help administer the modems. Those logs are DHCP related.

    Create firewall rules on the WAN:




    Go to your WAN interface page and uncheck "Block Private Networks"

  • Wow, that was fast.  Thank you very much!  :D

    Can you explain the block rule parameters, that is:

    Interface, Protocol, Source, Destination etc.

    Thank you again.


  • Just block all.

    • * * * * none

    Good Luck!
