but that's something your app would have to do itself, there's no railway firewall

Im hosting the server for sending POST requests only but i only want specific addresses to be able to do that
weak spoke
that's something your app would have filter itself, there's no railway firewall

Do you know if thats possible using java springboot? sorry im kind of new to this
weak spoke
code up a middleware for it, have the middleware only pass requests if the requests come from a local IP address (so railway itself can healthcheck your app) or the single IP that you have whitelisted, it's a few if statements, nothing complicated
make sure you are reading the real ip addresses from the X-Forwarded-For header
hoary condor
what do you mean?
weak spoke
can't explain it any better than that
hoary condor
what is the x forwarded for header?
weak spoke
that question can be answered with a quick Google search
hoary condor
youre right
okay thanks for your help i think i got it from here, make a file filtering the ip and only pass the requests if the ip matches
weak spoke
you'll need to allow local ip's or else railway might think your app is dead

By allowing local ips, do you mean adding 127.0.0.1 to the whitelist or do i need to do additional steps?
hoary condor
i am unfamiliar with working with this, but from what i understand, i need to allow the ranges 192.168.0.0/16 ,10.0.0.0/8,
127.0.0.1, as well as the ip addresses i am whitelisting in my program

correct

Everything seems to be working as intended. Thank you so much for your help.
