Linux/NetworkManager¶
Installing the VPN client¶
Note
The solution is based on openconnect package and therefore requires proper support for Global Protect protocol there in. Read Linux/Command Line to check if your Linux distribution is known to have problems with the Global Protect protocol implementation.
RHEL/Rocky/AlmaLinux/Fedora¶
Open a terminal and type there:
sudo dnf install epel-release
sudo dnf update epel-release
sudo dnf install NetworkManager-openconnect-gnome
Settig up the VPN connection¶
Click with the mouse on the right upper corner of your GNOME desktop (where the icon for WiFi and Ethernet connectivity is placed). Then in the diplayed menu click on the “Settings” button (see where the red arrow points at in the picture below):
In the “Settings” window choose “Network” (1) and then press on the “+” sign (2) as it shown below:
In the selection next choose “Multi-protocol VPN client (openconnect)”:
Set “Discoverer” as a name of the connection (1), choose “Palo Alto Networks GlobalProtect” from “VPN Protocol” menu (2), enter start.discoverer.bg as “Gateway” (3), and press “Add” to save the configuration (4):
That will bring back the set-up to “Network” in “Settings”, where the newly created VPN configuration profile will appear in the list of configurations under the name “Discoverer”.
