Also because of this I suppose I cannot access internet in firefox.
I don't know what is the problem as default route is there.
When I did not add line
DNS1=192.168.1.1, I could ping 192.168.1.1 but after addition of that of that line I cannot.
Either way I get heaps of errors and cannot access internet and this is the problem statement.
Any ideas to resolve ?

The traceroute command might be your best friend in a situation like this.
Likewise dig to request a DNS-lookup and see where the answer came from.
By comparison to yours, my interfaces file entry for the primary NIC is very short:
Code:
auto enp0s3
iface enp0s3 inet dhcp
# This is an autoconfigured IPv6 interface
iface enp0s3 inet6 auto
dns-nameservers 8.8.8.8 8.8.4.4
You have a lot of other options in there. Perhaps one of them is the problem.
And my route-command output is also different – no link-local for instance:
Code:
$ route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.1.1 0.0.0.0 UG 0 0 0 enp0s3
192.168.1.0 * 255.255.255.0 U 0 0 0 enp0s3
192.168.56.0 * 255.255.255.0 U 0 0 0 enp0s8

Centos 7 makes you "connect" each time unless you change the default behavior.
Does it have a window manager?

Looks like you manually configured the ifcfg-enp0s3 file. If networkmanager is running it will still want to control the interface. Check out the following link.

Hi sysmicuser,
Here is something to look at, perhaps, from the networking side of things :
I use the bridged adapter method for several VB VMs. Depending on your network security and DHCP setup, you may have to follow steps like whitelisting the virtual MAC address the VM creates in your network hardware (router / switch / access point ..)(make sure there are no conflicts) and if you're using DHCP reservations, add the appropriate entry for the new MAC as well. If you're using static addressing, make sure that is set up appropriately as well. Essentially, using the bridged adapter option is like adding a new network interface adapter to your network.
Cheers,
|

Dear All,
Many thanks for your fantastic responses. Issue is resolved. I changed adapter in Virtualbox settings and it was all good.
