Dnsmasq issues?

Question

Hi. I'm trying to set up wi-fi spot using hostapd & dnsmasq. Everything seems to be okay, but dnsmasq doesn't assign an ip address to client machine.
hostapd.conf (no encryption atm., just to test conf):
interface=wlan0
driver=nl80211
logger_syslog=-1
logger_syslog_level=2
logger_stdout=-1
logger_stdout_level=2
ssid=test
hw_mode=g
channel=6
dnsmasq.conf:
interface=wlan0
dhcp-range=192.168.0.50,192.168.0.150,255.255.255.0,6h
console output:
[*@* ~]$ sudo /usr/bin/dnsmasq -qd
dnsmasq: started, version 2.60 cachesize 150

wireshark shows 0 outgoing packets, only DHCP Discover packets from client machine.
What did i miss ?

Netmask part of dhcp-range parm is superfluous in your case, try to drop it. It's also strange that in the conf you have a lease time of 6h while the dnsmasq daemon says 12h on start.
Also if you set both interfaces manually, can you ping each other?
Hi, thanks for reply.
Changed "dhcp-range=192.168.0.50,192.168.0.150,255.255.255.0,6h" to "dhcp-range=192.168.0.10,192.168.0.30,6h", same result. Different lease time is my copy/paste fault, i've changed lease time, to make sure dnsmasq reading from the same conf file i've edited. If i connect my wlan0 (intranet) with eth0 (ISP) with bridge, my LAN client machine getting an ip from my ISP. Wireshark shows ping-request packets coming from LAN to my wlan0 interface, but theres no ping-reply packets (in Wireshark/Lan machine). DHCPd seems to work fine with ip address offering, but no ping-reply's.
