Missing \ n to run molecule correctly here |

@tricovictor Do you need sth from me to fix the PR? |

Hi @nkakouros. I not is acquainted with Molecule but the task "Set IPv6 forwarding in the sysctl file and reload if necessary" in /task/system/fordwarding.yml is reporting:
I suppose it is solved as the task but from IPV4 by placing: |
| sysctl_set: true | ||
| state: present | ||
| reload: true | ||
| when: not lookup('env', 'IN_MOLECULE') | d(true, true) | bool and openvpn_ipv6_server is defined |
| reload: true | ||
| when: not lookup('env', 'IN_MOLECULE') | d(true, true) | bool | ||
|
|
||
| - name: Set IPv6 forwarding in the sysctl file and reload if necessary |

Could you also rename the previous task to say IPv4?
| # TCP or UDP server? | ||
| proto {{ openvpn_proto }} | ||

| {% if openvpn_ipv6_enabled %} |

Why do you leave the non-ipv6 options outside of a conditional? Does this work?

I couldn't find an option named route-ipv6-default. Where is this documented?
Also, why do you need lines 86-87 unconditionally when ipv6 is used?

openvpn_ipv6_server is defined will always be true. This variable is defined in defaults/main.yml as an empty string, what will matter in this template is if it's still empty or not.
According to the OpenVPN wiki
There are 2 ways to add IPv6 addressing and pool options to the server, similar to what OpenVPN supports for IPv4: using a helper-directive, and by expanding the helper-directive. The expansion is required if you do not wish to use the automatic values the helper-directive supplies.
- therefore
ifconfig-ipv6will be a complementary and optional configuration route-ipv6-defaultdoesn't exist, it's optional, and can be pushed with the variableopenvpn_ipv6_route_rangeswhich is defined as an empty list by default.

I added to this PR the fix to the IP forwarding discussed here, since it's necessary for both IPv4 (#159) and IPv6. Do you think that something else is missing to merge this PR? Please note that we (@UdelaRInterior) are an organization. @tricovictor, @ulvida, and I (@santiagomr) are working together on this fork. |

openvpn_ipv6_enabled is defined for ipv6 support.
Also openvpm_ipv6_route_ranges, where we define an array of network ranges to use.
For example:
openvpn_ipv6_route_ranges:
