[Solved] Sharing ethernet via wi-fi with NetworkManager and dnsmasq

I want to share my ethernet connection to my android phone. So I installed dnsmasq for working as dhcp server.
Here are my configs:
/etc/resolv.conf

search telecom.by
nameserver 127.0.0.1
nameserver 8.8.8.8
nameserver 213.184.225.37
nameserver 213.184.224.254

/etc/dnsmasq.conf

user=dnsmasq
group=dnsmasq
port=53
cache-size=1000
domain-needed
bogus-priv
interface=wlp8s0
dhcp-range=192.168.1.2,192.168.1.150,12h
dhcp-host=MAC-ADDRESS,192.168.1.2
#dhcp-authoritative

The I've created new Wireless (Share) connection in network manager:

Now I can connect via my phone to the wi-fi network and access local servers, use airdroid and unified remote programms. But when I want access external web-resource such as google.com or archlinux.org the loading bar in the browser hangs and nothing is loaded.
So I have two questions:

• How to setup network manager in Automatic method in ip-v4 tab

• What should I do to access external websites from my phone via this wi-fi network

Can you hit web sites by address? for example, 66.211.214.131  (archlinux.org)?

So I was wrong. To share internet connection you need use hostapd. With create_ap all works pretty well https://bbs.archlinux.org/viewtopic.php?id=162895

If someone finds this by google, try:

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

where eth0 is the outgong connection.
