<html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div>I am trying to migrate from dhcpd to dnsmasq for my home network, without much luck.</div>
<div> </div>
<div>I use the following simple configuration file:</div>
<div> </div>
<div>
<div>port=0</div>
<div>interface=lan<br/>
bind-interfaces</div>
<div>dhcp-authoritative<br/>
dhcp-range=192.168.69.32,192.168.69.95,2h<br/>
dhcp-option=option:router,192.168.69.1<br/>
dhcp-option=option:dns-server,192.168.69.1</div>
<div>log-dhcp</div>
<div> </div>
<div>My lan interface is configured as follows:</div>
<div> </div>
<div>6: lan: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000<br/>
link/ether 00:c0:ca:89:35:9c brd ff:ff:ff:ff:ff:ff<br/>
inet 192.168.69.1/24 scope global lan<br/>

inet 192.168.69.2/24 scope global secondary lan<br/>

valid_lft forever preferred_lft forever<br/>
inet6 fe80::7c2b:c1ff:fec3:674d/64 scope link<br/>

<div> </div>
<div>in the log, when I start dnsmasq, I can see:</div>
<div> </div>
<div>Jan 02 11:25:11 archimede systemd[1]: Starting A lightweight DHCP and caching DNS server: dhcp...<br/>

Jan 02 11:25:11 archimede dnsmasq-dhcp[8255]: DHCP, sockets bound exclusively to interface lan</div>
<div> </div>
<div>and nestat shows dnsmasq listening on UDP 0.0.0.0 port 67.</div>
<div> </div>
<div>However it does not work. Using tcpdump, I can see incoming dhcp lease requests from clients, but there is no server response. I know the tcpdump command I am using is correct, because if I switch back to dhcpcd, I can see both dhcp client requests and server replies.</div>

<div>What did I miss? Thanks</div>
