I ' m assuming the docker container is making use of the docker 0 interface , so you ' ll need to change your forward rules referencing 192 . 168 . 255 . 024 . E . G . change line 12 of the most recent gistfile to iptables A FORWARD i docker 0 d 192 . 168 . 255 . 024 j ACCEPT and line 23 to iptables A FORWARD o docker 0 s 192 . 168 . 255 . 024 . This is assuming that the 192 . 168 . 255 . 024 subnet is residing in the docker container . I ' m not too familiar with docker , so take the above with a grain of salt . <| sep |> This is why I really love the War Stories formula , the potential to add more content is great , as you say , 1 mission per packetc . I ' m inclinded to think they ' ll add say 3 to a new French campaign for it ' s release , then Russia and hopefully a German DLC afterwards . Also shows how big this can be for a WW 2 followup that is almost a certainty at some point . Brits in North Africa Americans in the Pacific , Russians in Russia , French in Europe , Germans during the end days . Plus even more that I can ' t even think of now .
