$ cat /etc/network/interfaces.d/wlan0 
iface wlan0 inet static
 address 172.31.31.172
 netmask 255.255.255.0

$ sudo systemctl restart dnsmasq
$ sudo systemctl status dnsmasq
$

$ sudo gzip --stdout --decompress /usr/share/doc/hostapd/examples/hostapd.conf.gz > /etc/hostapd/hostapd.conf
$ sudo sed --in-place 's|DAEMON_CONF=|DAEMON_CONF=/etc/hostapd/hostapd.conf|' /etc/hostapd/hostapd.conf
$ sudo editor /etc/hostapd/hostapd.conf
$ sudo systemctl daemon-reload
$ sudo systemctl restart hostapd
$ sudo systemctl status hostapd
$

• IPTABLES(8) – iptables/ip6tables — administration tool for IPv4/IPv6 packet filtering and NAT

iptables --table nat --append POSTROUTING --out-interface wlan0 --jump MASQUERADE
