Setup

1. Get a server

Recommended Specs

  • Type: VPS or dedicated
  • Distribution: Ubuntu 16.04 (Xenial), 18.04 (Bionic) or 20.04 (Focal)
  • Memory: 512MB or greater

2. Add a DNS record

Create a DNS A record in your domain pointing to your server's IP address.

Example: subspace.example.com A 172.16.1.1

3. Enable Let's Encrypt

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).

Usage

Example usage:

$ subspace --http-host subspace.example.com

Command Line Options

flag default description
http-host REQUIRED: The host to listen on and set cookies for
backlink / OPTIONAL: The page to set the home button to
datadir /data OPTIONAL: The directory to store data such as the WireGuard configuration files
debug OPTIONAL: Place subspace into debug mode for verbose log output
http-addr :80 OPTIONAL: HTTP listen address
http-insecure OPTIONAL: enable session cookies for http and remove redirect to https

help Display help and exit

Environment Variable Options

variable default description
SUBSPACE_IPV4_POOL 10.99.97.0/24 IPv4 Subnet to use as WireGuard subnet
SUBSPACE_IPV6_POOL fd00::10:97:0/112 IPv6 Subnet to use as WireGuard subnet
SUBSPACE_NAMESERVERS 1.1.1.1,1.0.0.1 Nameservers to use, by-default those of Cloudflare.
SUBSPACE_LETSENCRYPT 1 Whether or not to use a LetsEncrypt certificate
SUBSPACE_HTTP_ADDR :80 HTTP listen address
SUBSPACE_HTTP_INSECURE false Enable session cookies for http and remove redirect to https
SUBSPACE_LISTENPORT 51820 Port for WireGuard to listen on

SUBSPACE_THEME green The theme to use, please refer to semantic-ui for accepted colors
SUBSPACE_BACKLINK / The page to set the home button to
SUBSPACE_DISABLE_DNS false Whether to disable DNS so the client uses their own configured DNS server(s). Consider disabling DNS server, if supporting international VPN clients

Run as a Docker container

Install WireGuard on the host

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.
echo "wireguard" > /etc/modules-load.d/wireguard.conf
echo "iptable_nat" > /etc/modules-load.d/iptable_nat.conf
echo "ip6table_nat" > /etc/modules-load.d/ip6table_nat.conf

# Check if systemd-modules-load service is active.
systemctl status systemd-modules-load.service

# Enable IP forwarding.
sysctl -w net.ipv4.ip_forward=1
sysctl -w net.ipv6.conf.all.forwarding=1

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.

# Your data directory should be bind-mounted as `/data` inside the container using the `--volume` flag.
$ mkdir /data

docker create \
    --name subspace \
    --restart always \
    --network host \
    --cap-add NET_ADMIN \
    --volume /data:/data \
    # Optional directory for mounting dnsmasq configurations
    --volume /etc/dnsmasq.d:/etc/dnsmasq.d \
    --env SUBSPACE_HTTP_HOST="subspace.example.com" \
    # Optional variable to change upstream DNS provider
    --env SUBSPACE_NAMESERVER_IPv4="1.1.1.1" \
    --env SUBSPACE_NAMESERVER_IPv6="2606:4700:4700::1111" \
    --env SUBSPACE_NAMESERVERS="1.1.1.1,8.8.8.8" \
    # Optional variable to change WireGuard Listenport
    --env SUBSPACE_LISTENPORT="51820" \
  # Optional variables to change IPv4/v6 prefixes
    --env SUBSPACE_IPV4_POOL="10.99.97.0/24" \
    --env SUBSPACE_IPV6_POOL="fd00::10:97:0/64" \
    # Optional variables to change IPv4/v6 Gateway
    --env SUBSPACE_IPV4_GW="10.99.97.1" \
    --env SUBSPACE_IPV6_GW="fd00::10:97:1" \
    # Optional variable to enable or disable IPv6 NAT
    --env SUBSPACE_IPV6_NAT_ENABLED=1 \
  # Optional variable to disable DNS server. Enabled by default.
  # consider disabling DNS server, if supporting international VPN clients
    --env SUBSPACE_DISABLE_DNS=0 \
