Network firewall

Zones and L2

Zones, interfaces, VLANs, and bridges on the appliance plane.

Goal

Build Layer‑2 foundations: security zones, physical/logical interfaces, VLANs, and bridges.

Prerequisites

Steps

  1. Open Network → L2.
  2. Create a zone (for example lan, wan, dmz) with a clear name and description.
  3. Create interfaces and assign each to a zone. Set kind, MTU, admin-up, and optional parent/MAC as needed.
  4. Add VLAN subinterfaces (name, VLAN id, parent interface, optional zone).
  5. Create bridges and list member interfaces (comma-separated in the form).
  6. Publish from Overview when ready for appliances to apply.

Tips

  • Zone names are referenced by firewall rules—keep them stable.
  • Bridges rely on the kernel datapath for MAC learning; ShieldGate stores membership and desired state.
  • Disable unused interfaces instead of deleting them mid-change when you need a quick rollback path.

Verify

  • Zones and interfaces appear under L2.
  • After publish, appliance apply status (Monitor) shows success for L2 objects (Linux datapath) or Mock reconcile.
