Hi Hasan,
In your video for installation, you mentioned use of Bridged Adapter as a preferred option with router, what about accessing the software when one is outside home and you can't access your router, will you still be able to connect to Oracle Apps without being on the internet with your router?
Regards

Usually you can access your router when you are outside home. You can access it using external IP. However put it like this if you are unable to access your router then no network option will work be it bridge or NAT.

Hi Hasan,
Though I am still waiting for some kind of response on a related query re- Oracle vm virtualbox has stopped working; but I hoping you meant that with bridged adapter, it's possible to access apps without being to the internet with this form of installation?

Sorry for the late reply.
You said "Though I am still waiting for some kind of response on a related query re- Oracle vm virtualbox has stopped working" If you have opened for a separate thread for this problem then I should reply to you question in that thread.
In Bridge network both the host machine and the guest machine are treated as separate machines on the network. The guest machine can access the internet as well. In the NAT configuration, the guest machine is behind the host machine on a private network. You cannot access internet from the guest machine but can see the guest machine from the host machine.
Having said that if you wish to access your guest machine from outside the network via internet then you can do that in Bridge configuration. You have to make few changes to your router configuration. You need for forward 8000 and 9000 ports to the internal IP address of the guest machine. Also you need to specify the external IP (internet IP) address of your router in the host file of the computer, that you are using to connect to the guest machine over the internet. Off courses these details are outside the scope of the videos as the purpose of the videos is to provide training on how to access Oracle installation on a guest machine through the host machine. You dont have to have internet on your system to do that.
