## Introduction

This patch series introduces a new direction for firewall rules: forward.
Additionally this patch series introduces defining firewall rules on a vnet
level.

## Use Cases

For hosts:
* hosts utilizing NAT can define firewall rules for NATed traffic
* hosts utilizing EVPN zones can define rules for exit node traffic
* hosts acting as gateway can firewall the traffic that passes through them

For vnets:
* can create firewall rules globally without having to attach/update security
  groups to every newly created VM

This patch series is particularly useful when combined with my other current RFC
'autogenerate ipsets for sdn objects'. It enables users to quickly define rules
like:

on the host level:
* only SNAT HTTP traffic from hosts in this vnet to a specific host
* restricting traffic routed from hosts in one vnet to another vnet

on the vnet level:
* only allow DHCP/DNS traffic inside a bridge to the gateway

Not only does this streamline creating firewall rules, it also enables users to
create firewall rules that haven't been possible before and needed to rely on
external firewall appliances.

Since forwarded traffic goes *both* ways, you generally have to create two rules
in case of bi-directional traffic. It might make sense to simplify this in the
future by adding an additional option to the firewall config scheme that
specifies that rules in the other direction should also get automatically
generated.

## Usage

For creating forward rules on the cluster/host level, you simply create a new
rule with the new 'forward' direction. It uses the existing configuration files.

For creating them on a vnet level, there are new firewall configuration files
located under '/etc/pve/sdn/firewall/<vnet>.fw'. It utilizes the same
configuration format as the existing firewall configuration files. You can only
define rules with direction 'forward' on a vnet-level.


Changes from RFC to v2:
* Fixed several bugs
    * SDN Firewall folder does not automatically created (thanks @Gabriel)
    * Firewall flushes the bridge table if no guest firewall is active, even
      though VNet-level rules exist
* VNet-level firewall now matches on both input and output interface
* Introduced log option for VNet firewall
* Improved style of perl code (thanks @Thomas)
* promox-firewall now verifies the directions of rules
    * added some additional tests to verify this behavior
* added documentation
