<p class="MsoNormal">Hi,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">We have an application where we want the clients to have fixed IPs and that the clients are all on the same
<b><u>subnet</u></b>.<u></u><u></u></p>
<p class="MsoNormal">It is not practical for our application to use the MAC adresses of the clients.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">This configuration below will assign a somewhat fixed IP based on the VLAN subnets but it is not exactly what we want.<u></u><u></u></p>
<p class="MsoNormal">The point is that we want each client to receive a fixed IP address based on their port in the switch.<u></u><u></u></p>

<p class="MsoNormal">So, my question is:<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Is there a way to assign fixed IP(v4) adresses in dhcpd.conf to clients based on their VLAN membership instead of their subnet?<u></u><u></u></p>
