How to get on the internet from within a Debian 10.3 HVM, when Debian says that it is connected to the network, but can't get on the internet by using Firefox from within the Debian HVM ?
I have created the Debian HVM by first downloading the DVD 1 file from here:
https://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/ to a VM. Then create a new HVM by using the GUI and boot the
ISO-file from another VM. And the installation run successful (without internet connection) according to the installer. After the installation I logged in to Debian 10.3, and then set up the network by writing the correct IP, netmask and gateway address according to the same HVM's "Qube Settings". And I have pressed "On" in the menu bar so that Debian says that it is connected to the cable network. But I still can't get on the internet. For example if I open Firefox, and write "test" in the html field, Firefox tell me that it can't connect to the server. And it is from the same pc I'm making this thread, so Qubes OS is connected to the internet.
I should probably also mention that I haven't installed any Qubes-tools yet. In case I should try that, please write which packages I shall install and where I can find them.
So I would like some suggestions on what I shall do to get on the internet by using Firefox from within the Debian HVM ?
