%description
This package sets up a VPN gateway, named sys-vpn, using openvpn.
It follows the method detailed in the Qubes docs,
 https://github.com/Qubes-Community/Contents/blob/master/docs/configuration/vpn.md
using nftables and CLI scripts.

The package creates a qube called sys-vpn based on the debian-12-minimal
template.  If the debian-12-minimal template is not present, it will
be downloaded and installed - this may take some time depending on your
net connection.

There are minor changes to the firewall rules on sys-vpn to ensure
blocking of outbound connections via eth0.
When the VPN is inactive only DNS traffic is allowed from sys-vpn.
When the VPN is active, no traffic is allowed except through the VPN
tunnel.
If the VPN uses Google's 8.8.8.8 server for DNS, this will be changed
to use Quad-9 servers.
sys-vpn will have the netvm set to the global default_netvm. Change this
as you will.

After installing, copy your openvpn configuration file or zip file
to sys-vpn.
Run setup_vpn to set up the VPN. 
There should be a menu item for this script - if you cannot see it, you may
need to refresh the application list in sys-vpn settings.
When finished, restart sys-vpn.

To use the VPN, set sys-vpn as the netvm for your qubes(s).
All traffic will go through the VPN.
The VPN will fail closed if the connection drops.
No traffic will go through clear.

If you remove the package, the salt files will be removed.
**The sys-vpn gateway will also be removed.**
To do this ALL qubes will be checked to see if they use sys-vpn.
If they do, their netvm will be set to `none`.

You can, of course, use template-openvpn to create other VPN gateways.
