## Overview

**LAN** is where you shape the inside of the network. The in-app help calls it
*"Configure your local network segments, wireless settings, VPN servers, and
security policies for optimal performance and security."* In practice it is the
step where you decide which of your devices sit on which routing path.

The project's core idea shows up here as a set of named networks: **Split** for
mixed traffic that gets routed by destination, **Domestic** for traffic that
should always go out the local link, **Foreign** for traffic that should always
go out the foreign link, and **VPN** for traffic that should go through the VPN
client. Each Wi-Fi SSID and each LAN port gets attached to one of them.

Which sub-steps you see depends on your router and your earlier answers.

## Before you start

- Decide which devices belong on which network before you start naming SSIDs.
- **VPN Server** and **Network Tunnels** only appear if you have a domestic
  link, because they need to be reachable over the local internet.
- **LAN EInterfaces**, **Network Tunnels** and **Network Subnets** are Advanced
  Mode only. In Easy Mode the wizard assigns ports and subnets for you.

## Steps

1. **Wireless.** Name your SSIDs and attach each to a network.
2. **LAN EInterfaces.** Assign each Ethernet port to a network bridge.
3. **VPN Server.** Let clients dial in to your router.
4. **Network Tunnels.** Build GRE, EOIP, IPIP or VXLAN tunnels to remote sites.
5. **Network Subnets.** Change the IP ranges behind all of the above.

## Reference

| Sub-step | When it appears |
