[Voyage-linux] DHCP server not working using dnsmasq config and nat.sh scripts

[Kim-man 'Punky' TSE]

My always working config are like this:  Wlan0 connects to another AP for outbound, wlan1 as AP and DHCP server (dnsmasq)

auto wlan0
iface wlan0 inet dhcp
         wpa-ssid <>
         wpa-psk <>

auto wlan1
iface wlan1 inet static
         address 10.1.20.1
         netmask 255.255.255.0
         broadcast 10.1.20.255
         hostapd /etc/hostapd/hostapd.wlan1.conf
         up nat.sh wlan1 eth0 "10.1.20.0/24"

/etc/dnsmasq.more.conf
dhcp-range=wlan0,10.1.10.10,10.1.10.250,24h
dhcp-range=eth1,10.1.20.10,10.1.20.250,24h
dhcp-range=eth2,10.1.30.10,10.1.30.250,24h
dhcp-range=eth3,10.1.40.10,10.1.40.250,24h
dhcp-leasefile=/var/tmp/dnsmasq.leases

The different is I don't use WEP but WPA/WPA2.  I use most of default settings in /etc/hostapd/hostapd.wlan0.conf.  Or 
perhaps you missed the first tag (eth1 or whatever) in "dhcp-range=eth1,10.1.20.10,10.1.20.250,24h"?

Punky
