But I think in your case, you will need to use bridge network instead of ipvlan0. Can you change that and try again?

</div>
<div>
<p>Hi everyone,<o:p></o:p></p>
<p>Has anyone successfully used the Kea Docker image (version 2.6.0) on Docker Desktop running on a Windows laptop? I'm facing issues with a simple scenario: my host machine has a network card connected to a device (Raspberry Pi) that needs to lease an IP from
the Kea Server. Unfortunately, the Raspberry device is not getting the IP. I would appreciate any help or advice on troubleshooting this setup.
<o:p></o:p></p>
<p>Also, if this seems to be a bug, how can I report it to ISC to get in touch and possibly have it resolved in a future release?<o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:12.0pt">Hi All - In my specific scenario, the Kea Server is running on Docker Desktop (WSL) on Windows 11 Pro with the following setup. The Raspberry Pi is directly connected to the “Ethernet” port via a LAN cable
on the Windows host machine and is supposed to receive a DHCP offer from the Kea Server. Wireshark shows that the “Ethernet” interface received the DHCP Request when the Raspberry Pi was plugged in, but somehow the Kea Server couldn't pick up this request.
Interestingly, when I run the udhcpc client on the Windows host machine using Docker with the command
<i>docker run --net kea-10-ipvlan --rm busybox sh -c "udhcpc -i eth0 -v",</i> the Kea Server successfully leases the IP. The windows firewall is turned off . It would be great if you could share any workarounds for this issue<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">Here is the logs from Kea Server. Unfortunately, the Raspberry is not getting the DHCP Offer. WhereAny have insight on this ?<o:p></o:p></span></p>
