Hi all,
I've been using dnrd and isc-dhcpd for several years on my LAN and
decided to give dnsmasq a try, to replace both.
dnsmasq works fine as dns server on my ADSL gateway/webserver/WAP, a box
running FreeBSD 8.1-release, but I am having difficulty getting dhcp
working. The current version in the ports collection is: v2.55
I have added these two lines to dnsmasqconf:
dhcp-range=192.168.2.2,192.168.2.15,168h
dhcp-range=192.168.3.2,192.168.3.25,12h
which correspond to the two internal network interfaces in my gateway
box, ethernet (192.168.2.1) and WiFi (192.168.3.1) respectively. I then
restart dnsmasq. However, the LAN client is unable to obtain a lease:
$ sudo dhclient -v eth0

On the server, I know that dnsmasq is listening on port 67:
$ lsof -Pni | grep :67
dnsmasq 58614 nobody 4u IPv4 0xc5982550 0t0 UDP *:67
What could be the problem here? Am I missing something?
Fwiw, isc-dhcpd works fine on the server.
Thanks.
