</div>I don't know about missing anything obvious, but i) can you also show<br>
the dhcp-host options you use for one host? Also, just in case, try<br>
with a tag that does not match the name of an interface (and make sure<br>
that you change it in the VLANs' dhcp-range options as well as in the<br>
hosts' dhcp-host options).<br></blockquote><div><br></div><div><div class="gmail_default" style="font-family:tahoma,sans-serif">Here's the configuration for the DHCP range used on one VLAN (on interface br1).</div>

<div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">What I thought Simon was suggesting was to allocate specific static addresses to the access points that are outside the ranges that are allocated to other clients. This would avoid the problem of dnsmasq allocating addresses to other clients that had already been allocated to the access points. What I'm missing here is how to reserve several addresses for a particular access point when all the requests use the same mac address. The requests will arrive on different interfaces (br0, br1, br2 etc) but I can't see how to use that in the dhcp-host configuration. That's why I think I'm missing something!</div>
