Hi Shobhith,

The client would have to support that option in order to do something useful with it.  Use tcpdump or wireshark to observe the packets between the server and client to see if the option is requested in the parameter request list and if it is returned.  You can also set the always send flag on the option so that it gets sent regardless.  But, again, the client would need to know what to do with the option before it would have any affect.

Thank you,

Darren Ankney

Hi,
I am trying to build a captive portal using kea DHCP.
I tried the standard option 160 and mentioned the URL to be redirected to as the value, but no luck.
v4-captive-portal       160     string
Please help me know if the option will work or how to configure it.
Thanks in advance.
