What will the broadcast address in the --dhcp-range configuration affect if not broadcast replies?<br><br><br><div class="gmail_quote">On Sun, Jan 24, 2010 at 3:39 AM, Simon Kelley <span dir="ltr"><<a href="mailto:simon@thekelleys.org.uk">simon@thekelleys.org.uk</a>></span> wrote:<br>

You were exactly right. The firewall was blocking outbound broadcast packets on the subnet. I'm not sure if this is correct, but my config specifies:<br>
<br>
dhcp-range=wireless,192.168.3.50,192.168.3.250,255.255.255.0,192.168.3.255,12h<br>
<br>
I think that's saying the broadcast address should be 192.168.3.255, but broadcasts attempts are actually going out on 255.255.255.255.<br>

255.255.255.255 is always a valid broadcast address on IP networks, and the correct one to use for DHCP.<br>
<br>
255.255.255.255 = limited broadcast address, propogates only on one network segment.<br>
<br>
192.168.3.255 = network broadcast address. May be routed to other network segments be suitably configured routers.<br>
<br>
I'm glad that's fixed. Probably worth a FAQ entry!<br>
