Hmm? Not following.<br>
<br>
I understood that RequestBroadcast=yes is necessary to make dhcp work<br>
on the Linux kernel bridge. Or is that a misunderstanding?<br>
<br>
What I am wondering about specifically is whether<br>
80-container-host0.network shall default to RequestBroadcast=yes, or not?<br>
<br>
Aso, if there are some networks that require the bit set, and others<br>
that require it unset, what about trying the other after not getting a<br>
reply on the first?</blockquote><div><br></div><div>Trying unicast, waiting some time and then trying broadcast, if a DHCP offer is not sent within that time limit, seems like a fair thing to do.
