- WireGuard VPN Protocol
- The most modern and fastest VPN protocol.
- Single Sign-On (SSO) with SAML
- Support for SAML providers like G Suite and Okta.
- Add Devices
- Connect from Mac OS X, Windows, Linux, Android, or iOS.
- Remove Devices
- Removes client key and disconnects client.
- Auto-generated Configs
- Each client gets a unique downloadable config file.
- Generates a QR code for easy importing on iOS and Android.
See the CONTRIBUTING page for additional info.
Recommended Specs
- Type: VPS or dedicated
- Distribution: Ubuntu 16.04 (Xenial), 18.04 (Bionic) or 20.04 (Focal)
- Memory: 512MB or greater
Create a DNS A record in your domain pointing to your server's IP address.
Example: subspace.example.com A 172.16.1.1
Subspace runs a TLS ("SSL") https server on port 443/tcp. It also runs a standard web server on port 80/tcp to redirect clients to the secure server. Port 80/tcp is required for LetsEncrypt verification.
Requirements
- Your server must have a publicly resolvable DNS record.
- Your server must be reachable over the internet on ports 80/tcp, 443/tcp and 51820/udp (Default WireGuard port, user changeable).

The container expects WireGuard to be installed on the host. The official image is subspacecommunity/subspace.
apt-get update
apt-get install -y wireguard
# Remove dnsmasq because it will run inside the container.
apt-get remove -y dnsmasq
# Disable systemd-resolved listener if it blocks port 53.
echo "DNSStubListener=no" >> /etc/systemd/resolved.conf
systemctl restart systemd-resolved
# Set Cloudfare DNS server.
echo nameserver 1.1.1.1 > /etc/resolv.conf
echo nameserver 1.0.0.1 >> /etc/resolv.conf
# Load modules.
modprobe wireguard
modprobe iptable_nat
modprobe ip6table_nat
# Enable modules when rebooting.

# Enable IP forwarding.

Follow the official Docker install instructions: Get Docker CE for Ubuntu
Make sure to change the --env SUBSPACE_HTTP_HOST to your publicly accessible domain name.
If you want to run the vpn on a different domain as the http host you can set --env SUBSPACE_ENDPOINT_HOST
Use --env SUBSPACE_DISABLE_DNS=1 to make subspace generate WireGuard configs without the DNS option, preserving the user's DNS servers.

Pull the latest image, remove the container, and re-create the container as explained above.
# Pull the latest image
$ sudo docker pull grigorov/subspace
# Stop the container
$ sudo docker stop subspace
# Remove the container (data is stored on the mounted volume)
$ sudo docker rm subspace
# Re-create and start the container
$ sudo docker create ... (see above)Thanks goes to these wonderful people (emoji key):
