If you want ollama to listen on all network devices on your machine then you’ll need to set the following environment variable:
export OLLAMA_HOST="0.0.0.0"
Then just start ollama with: ollama serve.
There is a nice FAQ how to run ollama as a server instance: ollama/docs/faq.md at main · ollama/ollama · GitHub
Also if your ollama server is behind a firewall (NAT etc) you’ll need to portforward the port from your firewall/router to your machine.
