I'm trying to configure an Oracle Linux VM - Virtualbox Version 5.2.8 r121009 (Qt5.6.2) - on my Windows 10 OS (Version 10.0.16299 Build 16299), but I can't navigate on Firefox Browser and my system isn't wired connected properly. I'm new to Linux, so probably I missed something.
I'm on private (corp) network with proxy. So I firstly configured Windows in Internet Options > Connections > Lan settings
Then I selected NAT connection in VBox and I configured wired connection with my Vbox Lan ip. I can ping my laptop but I can't ping www.google.com, for example.
So I tried Automatic DHCP, I can ping my laptop, corp. Lan and google, but I can't use repository
Trying other mirror. http://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/repodata/repomd.xml: [Errno 14] curl#7 - "Failed connect to yum.oracle.com:80; Connection refused"
Please help me to solve this connection issue with detailed steps, because I'm not expert in this environment.
