Firewall log udp



  • My firewall log is filled with blocked private ip  udp entries
    Mar 22 19:02:50 WAN 10.138.xx.1:67 255.255.255.255:68 UDP
    block
    Mar 22 19:02:54 WAN 10.138.xx.1:67 255.255.255.255:68 UDP
    block
    Mar 22 19:02:56 WAN 10.138.xx.1:67 255.255.255.255:68 UDP
    block
    Mar 22 19:03:38 WAN 10.138.xx.1:67 255.255.255.255:68 UDP
    block
    Mar 22 19:03:42 WAN 10.138.xx.1:67 255.255.255.255:68 UDP

    I was wondering if someone knows what that is and how to stop logging it w/o disabling blocking private networks?



  • DHCP



  • Add a blocking rule on your WAN 10.0.0.0/8 172.16.0.0/12  and 192.168.0.0/16  then uncheck the "private networks" on the WAN interface page. Put them at the top.

    Cable systems generally use addresses in the 10.0.0.0/8 block for system administration.



  • Thanks so much for that, it worked perfect.



  • big thanks from me, too!  ;D
