If you're looking for a simple way to deploy this to the Amazon Web Services Cloud, check out the [Factorio Server Deployment (CloudFormation) repository](https://github.com/m-chandler/factorio-spot-pricing). This repository contains a CloudFormation template that will get you up and running in AWS in a matter of minutes. Optionally it uses Spot Pricing so the server is very cheap, and you can easily turn it off when not in use.
## Using a reverse proxy
If you need to use a reverse proxy you can use the following nginx snippet:
```
stream {
server {
listen 34197 udp reuseport;
proxy_pass my.upstream.host:34197;
}
}
```
If your factorio host uses multiple IP addresses (very common with IPv6), you might additionally need to bind Factorio to a single IP (otherwise the UDP proxy might get confused with IP mismatches). To do that pass the `BIND` envvar to the container: `docker run --network=host -e BIND=2a02:1234::5678 ...`
## Troubleshooting
### My server is listed in the server browser, but nobody can connect
