There are two cases what a computer can do, when it has to forward an IP package:
First case: Say the destination IP of the incoming package is
10.20.30.40 and the interface on which the package arrives is configured to be
10.20.30.1 netmask 255.255.255.0. This is, the
packages destination subnet and the interfaces subnet are the same.
Then your OS will forward the package to the broadcast
(it says "Here is a package that is addressed for someone in my own
hood, so please take it!").
Second case: Say the destination IP of the incoming package is
10.20.40.40 and the interface on which the package arrives is configured to be
10.20.30.1 netmask 255.255.255.0. Then the
destination address lies outside of the interfaces subnet. So it does
not know where to send it. So it forwards it to the default gateway
which in turn tries to find the destination.
In your case the default gateway is exactly the same as your interface IP. That means: When your computer does not know where to send a package it sends it to itself respectively to one of its own interfaces. That sounds strange - and it is. An interface gateway should be in the same subnet as the interface itself, but it should never BE itself. You need another default gateway in the same subnet to be happy.
If you don't know your default gateway for this interface, so try to get a valid default gateway for this interface via DHCP configuration (configure this interface to be a DHCP client).
In the case you are working in a VM (I see it is Virtual Box) try to find out the IP address of the "Virtual Box Host Only Adapter" on your host machine (command: ifconfig or ipconfig). Then configure the IP address of the VM host only adapter to be the default gateway of your VM guest.
On your host machine your should activate ipv4-forwarding and NAT to get internet access:
echo 1 > /proc/sys/net/ipv4/conf/all/forwarding
iptables -t nat -A POSTROUTING -o <interface on which you have the i-net access> -j MASQUERADE
If your want to use the "Host Only Adapter" then it may be possible, that you first have to create an "Host Only Network" under File->Preferences choosing the tab "Host Only Networks"...
