VPN¶
What is the purpose of VPN connection in IsardVDI?¶
The user establishes a VPN tunnel in IsardVDI to access their desktops using the RDP VPN viewer or simply to establish communication between the host machine and user desktops (e.g., accessing them via an SSH connection).
How to establish the user VPN tunnel¶
Firstly, the Wireguard VPN network interface must be active on all the desktops that need to be visible in the VPN tunnel, either by editing their "Hardware" or creating them directly with that network interface.
Secondly, access the user's dropdown menu and select the VPN option, which will download a .conf file to the host machine.
To establish the connection, the WireGuard program is used. Depending on the host machine's operating system, download, install, and use the program as explained below.
With Linux host¶
After downloading the VPN .conf file, run the following commands in the terminal:
$ sudo apt install wireguard
$ sudo mv /download/path/isard-vpn.conf /etc/wireguard
$ wg-quick up isard-vpn
The user's VPN tunnel is now properly established. To test its functionality, you can start the user's desktops and ping their IP addresses from the host machine:
root@debian:~# ping 10.2.91.193

With Windows host¶
Download WireGuard for Windows using this link, open the program, and import the recently downloaded VPN .conf file.
The user's VPN tunnel is now properly established. To test its functionality, you can start the user's desktops and ping their IP addresses from the host machine:
C:\Users\windows>ping 10.2.91.193
