VPN

To ensure connections between our Nextbit local machines and cloud resources or any internally developed application, we must use a Virtual Private Network (VPN).

This VPN has both an IPv4 and IPv6 static IP address:

  • 15.161.21.74

  • 2a05:d01a:d27:7543:8f6c:be3a:1cf9:18a3

The hostname of the VPN server is subspace.nextbit.it, and it is hosted in eu-south-1 (Milan).

Connect to VPN

To connect to our VPN for the first time, you need to:

  • login into our website https://subspace.nextbit.it/ using “Login with Microsoft Online” with your Office 365 account.

  • follow the instructions for your operating system, and download the config file

You have to follow this procedure just once, to initialize the VPN. The following times you’ll need only to start the client locally.

The VPN is based on Wireguard, that has clients for all the OS.

On Linux-based system it doesn’t have a GUI. Install it on Ubuntu 20.04 with:

sudo apt install wireguard
ln -s /usr/bin/resolvectl /usr/local/bin/resolvconf

or on previous versions with:

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository ppa:wireguard/wireguard
sudo apt install wireguard
ln -s /usr/bin/resolvectl /usr/local/bin/resolvconf

Prevent the config file to be publicly accessible with:

chmod 400 ./wg0.conf

Finally, to connect to the VPN, use the command line:

wg-quick up ./wg0.conf

where ./wg0.conf is the location and the name of your configuration file.

In the same way, to disconnect do:

wg-quick down ./wg0.conf
