#### Prerequisites:
1. `docker` and `docker-compose` (Alpine: community repository; https://docs.genesys.com/Documentation/System/8.5.x/DDG/InstallationofDockeronAlpineLinux), `git`, and `curl` are installed (Alpine: `apk add`). You may also want to make docker run at boot: `rc-update add docker boot`.
2. `eth0` is the **LAN** or **WAN** interface supporting external routing, DNS, etc., and is the **bridged** interface to a router that will statically route the entire desired network subnet (i.e. x.x.0.0/21) through it. You may also have an `eth1` (and so on, so forth) that you statically configure for your entire, wide subnet (i.e. x.x.0.0/21) if you want to use two physical adapters.

You may also have an `eth1` (and so on, so forth) that you statically configure for your entire, wide subnet (i.e. x.x.0.0/21) if you want to use two physical adapters. If you do have more than one interface, make sure that `internal_interface` is set to the interface that can route your personal Lixonet subnets, and not your WAN interface with a default gateway.
4. `tun` and `tap` are in `/etc/modules` to load at boot (https://www.cyberciti.biz/faq/linux-how-to-load-a-kernel-module-automatically-at-boot-time/) and the system has been rebooted afterwards.
5. `sigil` is installed (`curl -L "https://github.com/gliderlabs/sigil/releases/download/v0.5.0/sigil_0.5.0_$(uname -sm|tr ' ' '_').tgz" | tar -zxC /usr/local/bin`)
6. IPv4 forwarding is on: `sysctl -w net.ipv4.ip_forward=1` and `iptables -P FORWARD ACCEPT` are run (and persisted) to allow IP forwarding. To persist these changes, see: https://wiki.alpinelinux.org/wiki/Configure_Networking, refer to "Save Firewall Rules".
