Rampart for OPNsense

Monitor and manage your OPNsense firewall from iPhone, iPad and Mac. Safe rule edits with auto-rollback, plus an AI assistant — on-device or your own Claude key.

Rampart puts your OPNsense firewall in your pocket — and on your Mac. Monitor everything at a glance, manage rules safely, and ask an AI assistant about your network in plain language.

MONITOR • Live dashboard: interfaces, gateways, throughput and DHCP leases • Firewall logs and IDS/IPS alerts • DNS activity with per-client breakdowns • Real-time status the moment something changes

MANAGE — SAFELY • View, add, enable, disable and delete firewall rules • Every change runs behind a 60-second savepoint that automatically rolls back if it drops your own connection • Redundant and duplicate rule detection

AI ASSISTANT • Ask "explain my rules" or "is my firewall secure?" in natural language • Two engines: fully private On-Device AI (Apple Intelligence), or Claude using your own Anthropic API key • Proposed changes are always shown for your approval — never applied automatically

PRIVATE BY DESIGN • Your firewall credentials are stored only in the device Keychain and never leave your device • On-device AI keeps everything local; the Claude option asks for explicit consent before sending any context • TLS certificate pinning (trust-on-first-use) for self-signed OPNsense boxes

NATIVE EVERYWHERE • Built for iPhone, iPad and Mac — not a web wrapper • Light and dark, Dynamic Type, and full accessibility support

Rampart connects to your own OPNsense router over your LAN, VPN or Tailscale, using an API key you create in OPNsense (System → Access → Users).
