Hello,
I am trying to do port forwarding as mentioned in this video - youtu.be/cPrjX5VFXrE, so that I can access my virtual machine for SampleApp607 on my host machine. I am selecting NAT and in Port Forwarding window I have given HostIP and hostport correctly but when I try to save the settings it says -
"Failed to save settings"
Details: Empty of null bridged interface name is not valid.
Result Code: E_FAIL (0x80004005)
Component: NetworkAdapterWrap
Interface: INetworkAdapter {e925c2aa-4fe4-aaf6-91c5-e9b8ea4151ee}
Can anyone please help.
Thankyou.

Re: Virtual box network adapter error
Please zip up the .vbox file for that VM and attach it to a post here.
Re: Virtual box network adapter error
Hello, attaching the vbox file kept at location- C:\Users\username\VirtualBox VMs\SampleAppv607p-appliance.
Not sure if this is sufficient to debug.
The actual VM file which VM box manager plays is of 24 GB so didn't attach that.
Thanks.

Re: Virtual box network adapter error
Bridged name not valid. Do you have a Bridged network card pointing to nowhere? Do you have a warning icon in the settings? A yellow triangle with an exclamation point? Hover over it...Vips wrote:Details: Empty of null bridged interface name is not valid.

Re: Virtual box network adapter error
You posted in "Windows Hosts" - is that what you have?
Anyhoo, it appears that at some time this VM had a second NIC enabled, configured for bridged mode, and bridged to host adapter "eth0". Unfortunately, on a Windows host the NIC name "eth0" is gibberish, since that's a Linux NIC name.
The adapter has since been disabled, but not deleted, so the wonky definition still exists and that's what VirtualBox is complaining about.
Unfortunately the UI will make this tricky to fix (it was never intended to cater for vbox files moved from Linux) so instead I've fixed it manually - see the attachment.

Re: Virtual box network adapter error
Thanks a lot.
Yes I have it on my windows.
File you have given is indeed working.
I am able to setup port forwarding, it doesn't throw E_FAIL error anymore.
However I am still unable to access VM from my local browser on my host machine.
It says "This site can't be reached. ERR_CONNECTION_REFUSED".
BI and database servers inside VM are up and running while I am trying to connect from my host machine browser.
Attaching the screenshot of port forwarding rules I have set in Vmbox settings as well the error I am getting in my host machine browser.
Is there any further setting missing which is blocking the host machine to connect to VM ?
Thanks for all support.

Re: Virtual box network adapter error
Sorry, someone else will have to help you with port forwarding, because I've never used it. If I wanted to browse into a guest I wouldn't have started with a NAT connection.

Re: Virtual box network adapter error
That's right. Start with the HostOnly connection. If you want internet access, then add a 2nd network adapter.
Please read the following: User Manual, ch. 6.2. Introduction to networking modes including the Overview table, which shows quickly what kind of connection is required to achieve what you want. And remember, you can always have more than one network card in your guest to cover multiple scenarios.
PS. Please crop your images to the important areas. We don't need huge pics of your whole desktop. And prefer PNGs instead of JPGs.
