ollamawg puts a WireGuard tunnel in front of Ollama, adds per-device access control, and gives you a dashboard on the host that shows who is connected, what they run, and who is knocking on the port. 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 it needs no root, no kernel module and no TUN device, on the server or on clients. Keys are standard WireGuard keys.

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.

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

Quickstart

On the machine running Ollama:

npm install -g @ollamawg/cli   # prebuilt binary, or:
go install github.com/himanshu-mamgain/ollamawg/cmd/ollamawg@latest

ollamawg init --endpoint your-public-ip-or-dns:51820
ollamawg add-peer --name laptop
ollamawg serve

init 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. Forward UDP port 51820 on your router or cloud firewall.

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

Features

Userspace WireGuard on Linux, macOS, Windows and the BSDs, with no admin rights needed on clients.
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 and admin actions.
- Traffic graphs per device for 1, 6 or 24 hours, plus token usage per model.
- Prometheus /metrics.
Dashboard: add devices and download their config, edit policy, block and unblock, and manage firewall rules. It is one embedded page with no CDN, so it works offline.
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.

Building from source

git clone https://github.com/himanshu-mamgain/ollamawg && cd ollamawg
go mod tidy          # first time only: records dependency checksums in go.sum
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.
