I'm following a tutorial from the following link
https://www.howtogeek.com/440752/protect-your-home-minecraft-server-from-ddos-attacks-with-aws/
to setup a proxy server to defend my home network from attacks. I'm wondering how to setup my router to only allow connections from the proxy server.
the proxy server is being run off of AWS Ec2 free tier.
how do I go about setting this up?
