Jogi,
http://christophertomasulo.com/how-to-use-the-obihai-202-cloud-file-sharingOnce you have this working you'll probably want to be able to access your share OUTSIDE your local network (outside your home or office). In order to do this you will need to do some Port Forwarding. If you don't know how to do this you may want to Google it. I won't be giving a tutorial for that in this short post (although I'll do a separate post if there is enough demand). Essentially what you want to do is have your router send all http: traffic to your public IP (can be checked on services like
http://whatismyipaddress.com) to the internal IP of the Obihai 202 device (the IP you used earlier).
It looks like you need to port forward port 80 to your OBi unit (Default http port of the OBi unit web page).
Does this help?
