Ubuntu 14.04 GRE туннелирует Открытый vSwitch 2.01

Я установил 2.0.1 openswitch версии, включенные с распределением Ubuntu 14.04.

Я настроил простое, Ну и дела туннелируют, и контейнеры проверяют с помощью ping-запросов друг друга, но любой поток данных заблокирован.

Это - ovs-vswitchd.log на машине, пытающейся вытягивать данные:

Туннель работал с той же конфигурацией Ubuntu 12.04 и Открытый vSwitch 2.1.2

Какова может быть проблема?
