Всем доброго времени суток.
Проблема:
Из любого контейнера, поднятого в системе, нет доступа во внешку.
ping 8.8.8.8 - тишина, 100% потерь.
Контейнер имеет свою собственную external bridge сеть.
Из контейнера УСПЕШНО пингуется интерфейс eth0.
net.ipv4.conf.all.forwarding=1 - установлено.
Docker демона перезапускал.
ufw - дизейблил.
Ubuntu 18.04, Docker 18.06
Уже понятия не имею куда копать.
