How to Install Free FortiClient VPN Client on Ubuntu 22.04 LTS

FortiClient is a security solution designed to reduce your computer’s vulnerability. The manufacturer advertises that the tool comes with virus protection, two-factor authentication, and WAN optimization, among other things.

However, the FortiClient user interface itself only contains the vulnerability scan and a tab in which you can set up a VPN connection for remote access.

The vulnerability scan indicates when, for example, an application is outdated, so there is potential for an attack and an update is urgently needed.

The abbreviation VPN stands for “Virtual Private Network”, a self-contained network that you can access from anywhere with the right access data. For example, do you log into the company network from your home office to use printers, hard drives, and your work e-mail inbox, or do you dial into your home network while on the go and conveniently control your smart home from afar? Universities also allow their students secure access to the university network via VPN.

FortiClientEdition

Zero Trust Security (ZTNA) – This allows remote workers to use ZTNA and VPN encrypted tunnels with URL filtering and USB device control. Central management via FortiClient EMS is included with the cloud editions.

Only available as EMS Cloud edition.

The VPN-only version of FortiClient offers SSL VPN and IPSec VPN but does not include any support. Here we are going to install this one…

Подключение Linux Ubuntu 20.04, 20.10, 21.04 к Forti VPN

Так уж получилось, что для удаленного доступа к работе приходится использовать Forti VPN.

В Windows за подключение отвечает отдельное приложение, а в Ubuntu 18.04 раньше использовал пакет из репозитория openfortivpn и GUI клиент с сайта https://hadler.me/linux/openfortigui/ .

Не феншуйно, но работало. Времени искать более правильное решение не было.

Сейчас, когда только-только вышла Ubuntu 20.04 работающего без ошибок GUI Forti VPN клиента еще не выпустили.

Прежде всего в репозитории я нашел для GNOME пакет network-manager-fortisslvpn-gnome. В результате его установки в настройках подключения появился пункт настройки VPN и возможность выбора типа подключения.

Безусловно это вселяло надежду, что получится отказаться от громоздкого GUI приложения.

После создания и настройки нового подключения появляется соответствующий пункт в панели управления.

Но вот незадача, не подтягиваются DNS сервера от DHCP сервера. После многих часов поиска ответа на вопрос что же происходит привели меня к следующему выводу. Оказалось, что наш VPN-cервер Forti использует SSL для шифрования, а его использование по умолчанию отключено в systemd.

Решение

Итого, чтобы настроить подключение к Forti VPN с шифрованием SSL и корректным использованием DNS серверов нужно:

1 – Установить network-manager-fortisslvpn-gnome

sudo apt-get install network-manager-fortisslvpn-gnome

2 – Открываем файл /etc/systemd/resolved.conf . Далее ищем строчку DNSOverTLS, раскомментируем ее и присваиваем значение opportunistic. Потом раскомментируем строку Domains и прописываем доменное имя DNS-сервера. После чего дописываем DNS.

[Resolve]
DNS=X.X.X.X
DNS=Y.Y.Y.Y
#FallbackDNS=
Domains=corp.yourdomain.com
#LLMNR=no
#MulticastDNS=no
#DNSSEC=no
DNSOverTLS=opportunistic
#Cache=yes
#DNSStubListener=yes
#ReadEtcHosts=yes

sudo systemctl daemon-reload
sudo systemctl restart systemd-networkd
sudo systemctl restart systemd-resolved

Затем переподключаем соединение или для избежания доп проблем вообще перезагружаемся.

Все, при новом подключении к VPN серверу DNS серверы должны начать использоваться системой.

Альтернативное решение

Есть всегда альтернативный способ прописать DNS-серверы вручную и для этого нужно:

2 – Затем открыть один из файлов в папке /etc/resolvconf/resolv.conf.d (head или tail)

3 – После чего прописать в файл информацию о DNS серверах.

Суть в том, что после установки resolvconf он начинает управлять DNS серверами и итоговый файл /etc/resolv.conf начинает формироваться на основе трех файлов:

Получается, что добавляя информацию в эти файлы мы автоматически ее добавляем в итоговый файл /etc/resolv.conf

Install FortiClient VPN Client from Fortinet Ubuntu Repos

Fortinet provides repos from which you can easily install FortiClient VPN Client from. However, as of this writing, the repos are not available for Ubuntu 20.04 Focal Fossa. Thus, use the method above to install FortiClient VPN on Ubuntu 20.04.

Install FortiClient VPN Client from Fortinet Ubuntu Repos on Ubuntu 18.04

To install Fortinet VPN from Fortinet Ubuntu repos, you first need to install the repository GPG signing key.

wget -O - https://repo.fortinet.com/repo/ubuntu/DEB-GPG-KEY | sudo apt-key add -

Next, create the Fortinet Ubuntu 18.04 repo;

echo "deb [arch=amd64] https://repo.fortinet.com/repo/ubuntu/ /bionic multiverse" | sudo tee /etc/apt/sources.list.d/fortinet.list

Next, update the package repos;

Check the available version of

apt-cache policy forticlient

forticlient: Installed: (none) Candidate: 6.0.8.0140 Version table: 6.0.8.0140 500 500 https://repo.fortinet.com/repo/ubuntu /bionic/multiverse amd64 Packages 6.0.6.0125 500 500 https://repo.fortinet.com/repo/ubuntu /bionic/multiverse amd64 Packages 6.0.5.0106 500 500 https://repo.fortinet.com/repo/ubuntu /bionic/multiverse amd64 Packages 6.0.4.0091 500 500 https://repo.fortinet.com/repo/ubuntu /bionic/multiverse amd64 Packages 6.0.3.0073 500 500 https://repo.fortinet.com/repo/ubuntu /bionic/multiverse amd64 Packages 6.0.2.0058 500 500 https://repo.fortinet.com/repo/ubuntu /bionic/multiverse amd64 Packages 6.0.1.0048 500 500 https://repo.fortinet.com/repo/ubuntu /bionic/multiverse amd64 Packages 6.0.0.0029 500 500 https://repo.fortinet.com/repo/ubuntu /bionic/multiverse amd64 Packages

As you can see the Fortinet repos do not provide the latest version of the FortiClient VPN as of this writing. Hence, better use the first method above instead.
