The process for setting up a client is For each new client, the following steps must be taken. For the sake of simplicity, we will create the config file on the server itself. This, however, means that you need to transfer the config file *securely* to your server as it contains the private key of your client. An alternative way of doing this is to generate the configuration locally on your client and add the necessary lines to your server's configuration. -??? info "All commands described below at once" +??? info "Script to generate clients automatically" + Script content: + + ```bash + #!/bin/bash + ipv4="$1$4" + ipv6="$2$4" + serv4="${1}1" + serv6="${2}1" + target="$3" + name="$5" + + wg genkey | tee "${name}.key" | wg pubkey > "${name}.pub" + wg genpsk > "${name}.psk" + + echo "# $name" >> /etc/wireguard/wg0.conf + echo "[Peer]" >> /etc/wireguard/wg0.conf + echo "PublicKey = $(cat "${name}.pub")" >> /etc/wireguard/wg0.conf + echo "PresharedKey = $(cat "${name}.psk")" >> /etc/wireguard/wg0.conf + echo "AllowedIPs = $ipv4/32, $ipv6/128" >> /etc/wireguard/wg0.conf + echo "" >> /etc/wireguard/wg0.conf + + echo "[Interface]" > "${name}.conf" + echo "Address = $ipv4/32, $ipv6/128" >> "${name}.conf" + echo "PrivateKey = $(cat "${name}.key")" >> "${name}.conf" + echo "" >> "${name}.conf" + echo "[Peer]" >> "${name}.conf" + echo "PublicKey = $(cat server.pub)" >> "${name}.conf" + echo "PresharedKey = $(cat "${name}.psk")" >> "${name}.conf" + echo "Endpoint = $target" >> "${name}.conf" + echo "AllowedIPs = ${serv4}/32, ${serv6}/128" >> "${name}.conf" # clients isolated from one another + # echo "AllowedIPs = ${1}0/24, ${2}/64" >> "${name}.conf" # clients can see each other + echo "PersistentKeepalive = 25" >> "${name}.conf" + + # Print QR code scanable by the Wireguard mobile app on screen + qrencode -t ansiutf8 < "${name}.conf" + + systemctl restart wg-quick@wg0 + ``` + + Run the script like + ```bash sudo -i cd /etc/wireguard umask 077 - name="client_name" - - wg genkey | tee "${name}.key" | wg pubkey > "${name}.pub" - wg genpsk > "${name}.psk" - - echo "[Peer]" >> /etc/wireguard/wg0.conf - echo "PublicKey = $(cat "${name}.pub")" >> /etc/wireguard/wg0.conf - echo "PresharedKey = $(cat "${name}.psk")" >> /etc/wireguard/wg0.conf - echo "AllowedIPs = 10.100.0.2/32, fd08:4711::2/128" >> /etc/wireguard/wg0.conf - - systemctl restart wg-quick@wg0 - - echo "[Interface]" > "${name}.conf" - echo "Address = 10.100.0.2/32, fd08:4711::2/128" >> "${name}.conf" # May need editing - echo "DNS = 10.100.0.1" >> "${name}.conf" # Your Pi-hole's IP - echo "PrivateKey = $(cat "${name}.key")" >> "${name}.conf" - echo "PublicKey = $(cat server.pub)" >> "${name}.conf" - echo "PresharedKey = $(cat "${name}.psk")" >> "${name}.conf" - - qrencode -t ansiutf8 -r "${name}.conf" + bash "10.100.0."
