Rate limiting and reverse proxy

Howdy! I'm just now getting to setting up my web app to be hosted via Railway. It's an Express app written in JS. When I hosted it locally, I had it set up behind a reverse proxy, so I'd set trust proxy' to 1 and call it good. I want to configure a rate limiter on my application to help protect some endpoints, but can't seem to find the proper trust proxy to set for this. No matter the number I set, requests still look like they're coming from the Railway proxy. Any suggestions for configuring this setting or setting up rate limiting for my application on Railway?
Solution:
if railways proxy is the only proxy your app sits behind then you want to pull the client ip from the X-Envoy-External-Address header https://utilities.up.railway.app/raw im sure there are express middleware to do this for you...

I am using that header for logging so I suppose I can use it for rate limiting as well. Thanks
