    Hi luas,

     

    Let us isolate the problem.  Kindly answer the questions below:

     

    a. Was DHCP Filtering on the GS748Tv4 switch working before?

    b. Is the DHCP server connected directly to port 50 (uplink port)?  

    c. How is everything connected?  It would be best if you post an image or screenshot of your detailed network setup.

    d. Have you tried to reboot the GS748Tv4 switch?  If not yet, kindly try it then check if the same problem will occur.

    e. Have you just newly updated the firmware of the GS748Tv4 switch to v5.4.2.30?  If yes, I suggest you to perform a factory reset then reconfigure the settings from scratch and check if the same problem will occur.  

     

     

    Regards,
