Я использую Ubuntu Bionic OS для моего устройства NanoPi M1 plus.
Я сделал роутер Wi-Fi, работающий в 2 режимах. eth0 <-> wlan0 & wlan1 <-> wlan0
Я могу запустить точку доступа с помощью интерфейса wlan0, но не могу подключить к нему свое устройство (мобильный телефон).

По этой ссылке я добавил правило iptables:
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo sh -c "iptables-save > /etc/iptables.ipv4.nat"
В чем здесь проблема? Почему я не могу подключиться к точке доступа?
