# OpenVPN
|
||||
|
||||
Install and configure OpenVPN, based on [our HowtoOpenVPN wiki](https://wiki.evolix.org/HowtoOpenVPN)
|
||||
|
||||
## Tasks
|
||||
|
||||
Everything is in the `tasks/main.yml` file.
|
||||
Some manual actions are requested at the end of the playbook, to do before finishing the playbook.
|
||||
|
||||
## Variables
|
||||
|
||||
* `openvpn_lan`: network to use for OpenVPN
|
||||
* `openvpn_netmask`: netmask of the network to use for OpenVPN
|
||||
* `openvpn_netmask_cidr`: automatically generated prefix length of the netmask, in CIDR notation
|
||||
|
||||
## TODO
|
||||
|
||||
* Make it compatible with OpenBSD
|
||||
* See TODO tasks in tasks/main.yml

# openvpn_lan default to 10."last 2 digit of main IP of server".0/24. For example, if the server IP is 192.0.2.42, then openvpn_lan will be 10.2.42.0/24
|
||||
openvpn_lan: "10.{{ ansible_default_ipv4.address | regex_search('([0-9]{1,3})\\.([0-9]{1,3})\\.([0-9]{1,3})\\.([0-9]{1,3})', '\\3', '\\4') | join('.') }}.0"
|
||||
openvpn_netmask: "255.255.255.0"
|
||||
openvpn_netmask_cidr: "{{ (openvpn_lan + '/' + openvpn_netmask) | ipaddr('prefix') }}"

You have to manually create the CA on the server with "shellpki init {{ ansible_fqdn }}". The command will ask you to create a password, and will ask you again to give the same one several times.
|
||||
You have to manually generate the CRL on the server with "openssl ca -gencrl -keyfile /etc/shellpki/cakey.key -cert /etc/shellpki/cacert.pem -out /etc/shellpki/crl.pem -config /etc/shellpki/openssl.cnf". The previously created password will be asked
|
||||
You have to manually create the server's certificate with "shellpki create {{ ansible_fqdn }}"
|
||||
You have to adjuste the config file "/etc/openvpn/server.conf" for the following parameters : local (to check), cert (to check), key (to add), server (to check), push (to complete if needed).
|
||||
Finally, you can (re)start the OpenVPN service with "systemctl restart openvpn@server.service"
|
||||
|
||||
Press enter to exit when it's done.
