175,000 Ollama Servers Are Exposed to the Internet Right Now. Yours Doesn't Have to Be

Ollama has no built-in authentication, so configuring it to listen on all network interfaces and forwarding port 11434 can expose an unrestricted inference API that allows outsiders to list, pull, delete, and run models, while also increasing exposure to known and future vulnerabilities. The walkthrough recommends keeping Ollama bound to 127.0.0.1:11434 and running Open WebUI on 127.0.0.1:3000, then using a Twingate Connector on the same host to provide outbound-only, identity-based remote access without opening inbound firewall ports. Users create private Twingate resources for the WebUI and Ollama endpoints, apply security policies through an identity provider, and connect from approved devices through encrypted tunnels. This approach is presented as reducing discoverability, limiting access by user or group, preventing direct internet access to Ollama, and offering a more controlled alternative to port forwarding or publicly exposed reverse proxies.
