ollamawg puts a WireGuard tunnel in front of Ollama and adds per-device access control. It gives you a dashboard on the host that shows who is connected, what they run, and who is knocking on the port, and a ChatGPT-style chat page for phones. You can block a device or an IP with one click.

It is a single Go binary. WireGuard runs in user space through wireguard-go and gVisor's network stack, so the server needs no root, no kernel module and no TUN device. Computers connect with ollamawg connect, which needs no admin rights either. Phones use the official WireGuard app, because the keys and protocol are standard WireGuard.

Firewall. Every UDP packet hitting the WireGuard port is checked against your IP and CIDR rules before WireGuard sees it. Every source is counted, including scanners that never complete a handshake.
WireGuard. Only devices whose public key you registered can complete a handshake. Each device gets one tunnel IP, and WireGuard guarantees that traffic from that IP really comes from that key.
Proxy. Inside the tunnel, a reverse proxy enforces each device's role, model allowlist and rate limit. It logs every request with its token counts, then streams the request to Ollama on loopback. It also serves the chat page at /chat.

Ollama itself stays on 127.0.0.1. Nothing outside the tunnel can talk to it.

Requirements

Ollama on the server, listening on 127.0.0.1:11434, which is its default. Pull at least one model, for example ollama pull llama3.2.
A UDP port that devices can reach. By default this is 51820.
- At home, forward UDP 51820 on your router to the server.
- On a cloud VM, open it in the security group.
Behind CGNAT this won't work as-is. Many home and mobile ISPs put customers behind carrier-grade NAT, where the router's WAN address is private (10.x, 100.64.x) and no port can be forwarded. You can still:
- use the server's LAN address as the endpoint, which works for devices on the same network;
- ask your ISP for a public IP;
- or relay through a small VPS.
See Troubleshooting.

Install

npm install -g @ollamawg/cli        # prebuilt binary for Linux, macOS, Windows and FreeBSD
npx @ollamawg/cli version           # or run it without installing
go install github.com/himanshu-mamgain/ollamawg/cmd/ollamawg@latest

Standalone binaries are attached to every GitHub Release. A Dockerfile is included; see Running as a service.

Quickstart

On the machine running Ollama:

ollamawg init --endpoint your-public-ip-or-dns:51820
ollamawg serve

init writes server.yaml and prints the dashboard password. Open http://127.0.0.1:8088 on the server, or reach it over SSH with ssh -L 8088:127.0.0.1:8088 server.

Add a laptop

ollamawg add-peer --name laptop        # writes laptop.yaml

Copy laptop.yaml to the laptop, then run:

ollamawg connect --config laptop.yaml
curl http://127.0.0.1:11434/api/tags      # any Ollama client works unchanged

The ollama CLI, Open WebUI, LangChain, Continue and any OpenAI-compatible client pointed at http://127.0.0.1:11434/v1 go through the tunnel. The chat page is at http://127.0.0.1:11434/chat.

Add a phone

ollamawg add-peer --name phone --qr    # prints a QR code

You can also use Add device in the dashboard, then Phone.

In the official WireGuard app (iOS, Android), tap + → Create from QR code and scan it.
Turn the tunnel on and open http://10.77.0.1:11434/chat.
Use Share → Add to Home Screen to open it like an app.

Ollama apps such as Enchanted or Reins work too: point them at http://10.77.0.1:11434.

Features

Userspace WireGuard on Linux, macOS, Windows and the BSDs, with no admin rights needed on the server or on computers.
Phones. Any device with the official WireGuard app connects by scanning a QR code. Only the server's tunnel address is routed through it, so the phone's other traffic is unaffected.
Chat page. A built-in, mobile-friendly chat interface at /chat, served inside the tunnel.
- Streaming replies, Markdown and code blocks, and a model picker limited to what the device is allowed to use.
- Chat history kept on the device, and Add to Home Screen.
- It has no separate login: the device's WireGuard key is its identity, and its policy applies.
Per-device policy:
- Roles: user for inference, readonly, admin for pull and delete, or custom path rules.
- A model allowlist, such as llama3.2,qwen3:*.
- A requests-per-minute limit.
Blocking:
- By device ID. The session is cut immediately and new handshakes are refused.
- By IP or CIDR. Packets are dropped before WireGuard.
- Default-deny mode, which admits only allowlisted networks.
Observability:
- Access log with device, public IP, model, status, latency and prompt/generated token counts. It can also be written to a JSON Lines file.
- Security events: connects, roaming, policy denials, firewall drops, logins and admin actions.
- Traffic graphs per device for 1, 6 or 24 hours, plus token usage per model.
- Prometheus /metrics.
Dashboard: add devices (as a config file or a phone QR code), edit policy, block and unblock, and manage firewall rules. It is one embedded page with no CDN, so it works offline.
Two-factor login. Optionally protect the dashboard with an authenticator app, such as Google Authenticator, Authy or 1Password. Turn it on from the dashboard or with ollamawg 2fa enable. Scripts and Prometheus then use an API token.
Hot reload. add-peer, block or a hand edit of server.yaml applies within 2 seconds without dropping sessions.
Safety checks. The server warns if Ollama is also reachable outside the tunnel or if the config file is world-readable. Configs are written with mode 0600.
Go library. You can embed the server, or call Ollama from Go code through the tunnel without opening a local port.

Commands

  block        block --device or --ip
  unblock      undo a block
  serve        run the tunnel, proxy, chat page and dashboard
  2fa          enable, disable or check two-factor dashboard login

Client
  connect      bring the tunnel up and expose Ollama on 127.0.0.1:11434
  status       check the handshake and this device's policy

Other
  keygen       print a WireGuard key pair

Limitations

Devices need to reach one UDP port on the server. There is no relay or NAT traversal. CGNAT connections need one of the workarounds in Requirements.
The dashboard has one admin account. Put a reverse proxy with SSO in front if several people manage it.
Chat history lives in each device's browser. It is not synced between devices or stored on the server.
No independent security audit yet. The cryptography comes from wireguard-go and gVisor. The policy layer is small and covered by end-to-end tests. See the Security model.

Building from source

git clone https://github.com/himanshu-mamgain/ollamawg && cd ollamawg
go test -race ./...
go build -o ollamawg ./cmd/ollamawg

Go 1.24 or newer is required. Cross-compiling works out of the box, for example GOOS=windows GOARCH=amd64 go build ./cmd/ollamawg.

Releasing

Releases are cut from main by .github/workflows/publish.yml:

In a PR, bump version (and its optionalDependencies) in npm/cli/package.json and Version in server.go. A test fails if they differ.
Merge the PR. The workflow publishes every npm package that's missing that version, using trusted publishing with provenance, then creates the GitHub Release with binaries.

A re-run finishes a release that stopped halfway.
