<p class="MsoNormal">I recently added a 2.5GB switch to my network. All devices, which are NAS devices, plugged into the switch have a reservation for their IP4 address except of course the NAS running dnsmasq which has a fixed address. I updated dnsmasq to
include the reservations and the following dhcp options.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">dhcp-option=tag:eth4,option:netmask,255.255.255.0 # set net mask (1)<o:p></o:p></p>
<p class="MsoNormal">dhcp-option=tag:eth4,option:router,0.0.0.0 # set router address (3)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">No address range is specified for eth4. When one of the NAS devices attempts to get an IP address I receive the following error message.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">no address range available for DHCP request via eth4<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Even though I have reservations for the devices they never receive their reserved address. If I add the range option then the devices receive their reserved address.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">dhcp-range=tag:eth4,192.168.122.100,192.168.122.199,255.255.255.0,3d<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Why do I need to specify a dhcp range when the devices have reservations? I don’t want a device that does not have a reservation on this subnet to be able to plug into the switch and get an address. Is this a bug in dnsmasq? If not is there
a way to accomplish what I am trying to do?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am running dnsmasq version 2.88.<o:p></o:p></p>
