Hello everyone,

I asked this question on r/aws a while ago, but I'd also like to gather insights from this community.

Here's my situation: I have a home network with GTPL ISP and I'm looking to set up a configuration where only my home network can access all of my EC2 instances.

I've already set up Dynamic DNS with my router, and I've attached a No-IP host URL that's working well. Even after renewing my public IP, it updates correctly in No-IP.

Now, my question is: How can I associate my DDNS host endpoint with EC2 instances so that only my home network has access?

Thank you!
