I recently migrated from Qubes 3.2 to 4.0 and it appears that the networking for all the template VMs is shut off by default.
To update the default debian-9 template, I turned networking on and attached it to sys-firewall. But when I run the template, it appears that I can't connect out to sys-net or to the outside world (any ping fails). Is this a configuration bug?
(In the meantime, how do I change the firewall to break through?)
Thanks,
