## Overview

The screen is titled **Domestic Network Connection**, described as *"Configure your domestic
network connection"*. It is the same screen as **Foreign WAN**, aimed at the
other link: the one from your local ISP. You choose an interface type, then the
interface, then the settings that type needs.

The domestic link is what makes the **VPN Server** and **Network Tunnels** steps
available later, because those services need to be reachable over the local
internet rather than through the foreign link.

In **Advanced Mode** you can add several domestic links, and the panel is headed
**Domestic WAN Links** with an **Add Domestic Link** button and the note
*"Create your first domestic WAN connection. You can add multiple links for load
balancing and failover."*

## Before you start

- Know which physical port the domestic link is plugged into.
- Have PPPoE credentials ready if your ISP uses PPPoE, or the static addressing
  details if the link is statically addressed.
- Ports already taken by the foreign link or a trunk are not offered here.

## Steps

1. Under **Interface Type**, pick **Ethernet**, **Wireless**, **SFP** or
   **LTE**.
2. Under **Select Domestic Interface**, pick the specific interface.
3. Fill in the settings for that type.
4. In Advanced Mode, use **Add Domestic Link** to add further links, then set
   the strategy on **LoadBalance & Failover**.
