Copy dnsmasq configuration file to get a backup and then make a new one.

dhcp-option=45,192.168.1.5 # netbios datagram distribution server
dhcp-option=46,8 # netbios node type
Note: You can extend the dhcp-range or change the IP address in the configuration.
Step 3: Setup iptables to forward the internet traffic from Ethernet to
wireless LAN
Next, make port forwarding enabled automatically on boot up.
