How to set up Internet in VBox, guest - Xubuntu 15.10, host-Windows 7, with a 4G modem (Dial-Up)?

Question

linux

I have Windows 7 SP1 (host) and Xubuntu 15.10 (guest). I tried to use all types of networks in the VM settings, but the Internet did not work with any of them, while only pings go (for example, up to 8.8.8.8), and http and other protocols do not work (at all). Xubuntu can't even resolve the google.ru address. I have a 4G modem, which is defined in the system after connecting to the network as Dial-Up. What can I do to make the Internet appear on the guest?
ifconfig - pastebin.com/F0htAsps

Answer 1

echo "nameserver 8.8.8.8" > /etc/resolv.conf

Answer 2

but the Internet did not work with any of them, while there are only pings (for example, up to 8.8.8.8), and http and other protocols do not work (at all).

Your DNS is not working in Xubuntu guest.
Set it up... maybe via DHCP.
