Hi,
I have virtualbox on Windows Server, i try to set up Oracle Linux 7.3 as new guest.
In Virtualbox:
Network: Bridged
Card: Intel Pro/1000 MT Desktop
Cable Connected
During Oracle Linux 7.3 install, connection to network fails:
Oracle Linux 7.3 unable to connect bridged network card

Is there any idea how to fix this?
Thanks in advance,
If you're using wireless, bridged and wireless don't always play nice. Bridged networking is outside the WLAN specification. It may or may not work. Some combinations of Routers/Access Points, WLAN cards and drivers work, some don't. See: Bridging & Wifi - Supported hardware and add your experience. Try to see if it works either with wired bridged or with NAT.

Wait a minute... If NAT works perfectly, and you're not using wireless, then it's got to be your router configuration. Can't help you with the specifics I'm afraid since I can't see its configuration.

This is already big help. What do you think which router configuration parameter can have affect on this? some DHCP parameters?
Thank you in adavnce,

Is this a newly created guest or did you copy it from somewhere?
Is there a chance that another system with the same MAC address is already on the network?
To add to what Martin said, here are some rules in my home router:
You're not allowed by default.
Your MAC address has to be explicitly added to the list of allowed guests.
Some MAC addresses are allowed only specific times (think of the children).
You have to have a 26-digit hexadecimal password.
But, as I already said:

But, since NAT is working, why are you making your life difficult? The thing is that at the installation stage you couldn't care less if you have or do not have an active connection. To get the updates? Big deal, you get them afterwards, when you'll have a lot more of troubleshooting weapons at your disposal...

I created myself the guest (not copied), MAC address is fine, i verified that this is unique.
and no, i don't wanna make my life difficult.
I need to run an oracle client in the guest OS, and i need to see other guests as well, so i need the bridged config.
I can set it up with NAT, but i am afraid i would not be able to resolve this after installation either.
Anyhow it still not resolved, will check router again.
