    Hi Guys,

     

    IAP configured with simple SSID Guest primary usage. for the VLAn Network assigned - default. Palo Alto firewall configured as DHCP Server range is 10.240.31.220 - 10.240.31.240. IAP IP address is 10.240.31.243.

    When the client connection to the IAP it gets a completely different IP address. PCAP from the Palo Alto attached and a screen shot of the IAP. This is driving me mad 

     

    Cheers,

    Mykhaylo

    It looks like you have two DHCP servers:  10.240.31.254 and 192.168.10.1 

     

    You need to resolve that.
