Unable to Access Owncloud applicance from Static Public IP and error while joining AD

Server
10

Hi Dmitry,

  1. I have edited host file and map the own cloud private IP to hostname, and internally able to browse with a name.
  2. When my public IP address hits my Linksys dd-wrt router, what ports should I open and forward? All problem lies here, any suggestions, please.
  3. When https://publicip/owncloud hits the router, how is it going to forward the request to private IP 192.168.1.120/owncloud?

Look forward your kind reply.

Thanks, much !!
