Greetings. I don't quite understand the broadcast flag, however I did encounter the "taking a very long time to obtain an IP" problem.
I'm on Windows 10. Router has dnsmasq 2.75. During Windows booting process, its firewall would deny any unicast packet from outside its own subnet, that including DHCP. Windows would try to request DHCP, then deny the reply, a few times. Solution is asking Windows to request a DHCP reply via broadcast: http://sysadministrivia.blogspot.jp/2011/04/dhcp-broadcast-flag-problem-with-dhcp.html Wish this help. 五月 2016.4 From: weiqiang...@hotmail.com To: dnsmasq-discuss@lists.thekelleys.org.uk Date: Fri, 1 Apr 2016 02:38:30 +0000 Subject: [Dnsmasq-discuss] dnsmasq does not respect BOOTP's broadcast flag Dear all, I got a router using dnsmasq-2.66 for DHCP services, and I encountered a bug that the dnsmasq server does not respond to my PC's DHCPREQUEST( normally it should respond with a DHCPNAK? ), so it takes an obvious long time to got a new IP for my PC. So, is this really a bug or it is just something wrong with my PC(Works well with other DHCP server)? At my first thought, I think it should be a bug that has been solved, so I reviewed the latest(ver.2.75) dnsmasq source code, however, neither did it care about this flag. I also attached a patch for this. _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
