This direction will be used for specifying rules on bridge-level
firewalls as well as rules on the cluster / host level that are for
forwarded network packets.
Since with the introduction of this direction not every type of
firewall configuration can contain all types of directions, we
additionally add validation logic to the parser, so rules with an
invalid direction get rejected by the parser.

We introduce a new type of firewall config file that can be used for
defining rules on bridge-level, similar to the existing
cluster/host/vm configuration files.

Add tests for validating the directions in the guest firewall
configuration. While I'm at it, I also added tests for validating
interface names, since this functionality did not get tested before.

which should not be possible

This is getting quite long. I know we already have such massive lines,
but I wonder if we should at least do something like
(log_level_(?:in|out|forward)|...)
(tbh I wouldn't even condense the `(tcp_flags|smurf)_log_level`, but
somehow `log_level_(in|out|forward)` IMO looks fine...
No strong feelings though, if you think this doesn't help the readability anyway.

could drop the double-space after the first `eq` ;-)
and maybe it's worth switching to
grep { $rule->{type} eq $_ } qw(in out forward group)

Enables us to use the new forward direction as an option when creating
or editing firewall rules. By introducing firewall_type we can switch
between the available directions depending on which ruleset is being
edited.

Add the configuration options for vnet-level firewalls to the options
component. Additionally add the new policy_forward configuration
option to the datacenter-level firewall as well.

This adds the ability to dynamically configure and change the base_url
for the firewall options. This is needed for the SDN firewall dialog,
that updates the firewall components based on the selected vnet. This
avoids having to reinstantiate the component every time the user
selects a new vnet.

This is not really true, I can not create rules on the forward chain of
VMs, can I?
I think the "Zones" section could benefit from some rewording because
IMO the Zone representation is not really fitting and also in the rest
of the article we are talking about 'Levels' and not 'Zones'.
I'd propose something like this:
Firewall rules can be created on 4 levels, Cluster, Node, Vnet, VM.
However, the Rules only act on the 3 levels Node, Vnet and VM.
The reason for this is the distributed architecture: if a firewall rule
is created at cluster level, it gets rolled out to all hosts and acts at
host level.
At host level the rules can act on and manipulate traffic from/into the
host. With the new proxmox-firewall based on nftables it is additionally
possible to create rules that act on and manipulate traffic passing
trough the host (forwarded).
The Vnet level is only available with the new proxmox-firewall. At Vnet
level the rules can act on and manipulate traffic passing through the
Vnet (forwarded).
At VM level the rules can act on and manipulate traffic from/into a VM.

Here I'd also add that it is dependent on the Level the Rule is applied to.
