Many repeated UDP requests - How to stop?



  • Hello everyone, here is a screenshot of the Firewall Log showing repeated UDP requests from different computers on the network. How do I track down to these IP addresses that are not part of my 192.168.200.0 network.

    I moved my network from 192.168.1.0/24 to 192.168.200.0/24 to meet some other requirement. 192.168.1.31 was my previous NTP server and is no longer at that IP.

    TIA!

    What do you want to do? You already know which IP's are trying to access something "forbidden".
    Do you want to find out WHERE these computers are?
    A magic glass ball might help ;)



  • Thanks for the reply.

    Yes, I know the IP addresses but they are not part of my current network (192.168.200.0), but the requests are coming from LAN. I am not sure if there is some obsolete data from my previous network (192.168.1.0) conifguration on some computers that I have to flush to avoid these requests.



  • Based on the timestamps in your screenshot, it would seem that these are recent activity.  It would seem like you have something going on in your network that is unintended.
