Is it possible to whitelist IPs on railway?
I want to setup cloudflare and then only allow cloudflare to make API requests to my backend hosted on railwat. Where can I add which IPs can only access the backend?

You can find all the IPs for a specific region here:
https://utilities.up.railway.app/cidr-list?value=us-west1
my question is how to block any incoming request if it's not from cloudflares IPs, directly on railway rather than my app itself (just like you can whitelist IPs on Ec2 instances etc..)
ooh I see what you mean
I don't think there's a place where you can do that on railway if not on your app
I see :/
fragly is correct, railway does not offer any firewall rules, this is something your app needs to handle
if im not wrong adding cloudflare is enough, if I only use my cloudflare custom domain I can add rules on there, and no one can bypass them
doesnt stop someone from accessing the railway domain of your app though
I believe I can remove the default generate railway domain
that way I force everyone to use my custom domain through cloudflare
you can still access the railway app via a railway domain, the cname value railway gives you
but thats random so it should be sufficient
just something to keep in mind
oh okay
