Network Card overview

This article refers to Platform v3.0.0. The current Platform version is v3.2.0.

Overview

The Networking card on the Node Details page is the single place to inspect and change the network configuration of an edge node. It exposes every physical interface on the device (Ethernet, WiFi, Mobile), the node's hostname, and a set of Advanced features — VPN, Proxy, Standalone Mode, IPTables, and VLANs — each with its own edit popup.

Every edit popup also includes an Enable Rollback toggle that protects you from misconfigurations (see Enable Rollback below).

Networking card UI

The card is split into two sections:

  • Interfaces — one row per physical interface (Ethernet / WiFi / Mobile). Each row shows the IP address with a copy-to-clipboard icon, the interface name with a status indicator (green = online, gray = offline), an edit pencil, and an options menu.
  • Advanced — toggles and edit shortcuts for VPN, Proxy, Standalone Mode, IPTables, and VLANs.

At the top of the card you also see the node's Hostname, with a "last update" timestamp and an edit pencil.

Enable Rollback

Every edit popup in the Networking card has an Enable Rollback toggle. When enabled, the node monitors connectivity after applying the new configuration; if it loses connection to Barbara Panel, it automatically reverts to the last known good configuration.

tip

Keep Enable Rollback active whenever you change networking configuration over the network — it prevents a typo in a netmask from leaving the node unreachable.

Adjust the hostname

Hostname edit popup

Hostname edit popup

The hostname identifies the node on local networks and in remote management systems.

  1. Click the edit pencil next to the Hostname shown at the top of the Networking card.
  2. Type the new hostname in the popup.
  3. Click Save.

Adjust a physical interface

Each interface popup exposes a slightly different set of parameters depending on the medium, but Metric, MTU, IP (static or DHCP), Netmask, Gateway, IP Aliases, and DNS servers are common across the three. IP Aliases let you attach more than one IP to the same physical interface — handy for hosting several services or segmenting traffic. DNS servers can be specified more than once for redundancy.

Ethernet

Ethernet interface edit popup

Ethernet interface edit popup

  1. Click the edit pencil next to the Ethernet interface you want to configure.
  2. Set Metric, MTU, IP (static or DHCP), Netmask, Gateway, IP Aliases, and DNS servers.
  3. Toggle Enable Rollback if you want the change protected.
  4. Click Save.

WiFi (WLAN)

WiFi interface edit popup

WiFi interface edit popup

  1. Click the edit pencil next to the WiFi interface.
  2. Set SSID, password, the Hidden SSID toggle if needed, plus Metric, DHCP/IP, IP Aliases, and DNS.
  3. Toggle Enable Rollback.
  4. Click Save.

Mobile

Mobile interface edit popup

Mobile interface edit popup

  1. Click the edit pencil next to the Mobile interface.
  2. Set APN, User and Password for the SIM, then Metric, IP, Netmask, Gateway, and DNS.
  3. Toggle Enable Rollback.
  4. Click Save.

Configure a VLAN

VLAN edit popup

VLAN edit popup

A VLAN (Virtual Local Area Network) is a logical subdivision of a physical network that groups devices regardless of their physical location. VLANs improve management, security, and traffic segmentation.

In the VLAN popup you can set:

  • VLAN ID — a number between 1 and 4094.
  • VLAN Name.
  • Metric and MTU.
  • IP (static or DHCP), IP Aliases, and DNS servers.

Toggle Enable Rollback to protect the change.

Configure the Proxy

Proxy edit popup

Proxy edit popup

A proxy sits between the edge node and external networks and can be used to enforce security, caching, or policy. The Proxy popup accepts:

  • URL of the proxy server (must include protocol, address, and port).
  • User for authentication.
  • Password for the user above.

For the full enable / disable flow (including the reboot that the change requires), read Configure the Proxy.

Activate the VPN

The VPN toggle lives in the Advanced section of the Networking card.

For the activation flow and how to connect to the node from your laptop with WireGuard, read Configure the VPN.

Configure IPTables

IPTables edit popup

IPTables edit popup

IPTables is the Linux firewall on the node. The IPTables editor lets you type rules directly, save them, and roll them back if connectivity is lost.

Toggle Enable Rollback to protect yourself from a firewall rule that would otherwise lock you out.

Summary

The Networking card centralises every change you can make to the network state of a node: interfaces and hostname in the top section, VPN/Proxy/Standalone/IPTables/VLAN in the Advanced section. Keep Enable Rollback on whenever you push a risky change, and use the dedicated articles linked above for the deeper VPN, Proxy, and Standalone Mode flows.
