How to block UDP traffic from specific countries in?

Question

I'm from India and I run game server on UDP port 27015. I'm using EC2 service. From past few months, we are facing DDoS attacks from outside India on my UDP port.

I tried enabling security groups to block Ips but it fails.

Is there any way to block non Indian UDP traffic on Amazon EC2?

Thanks!

Answer 1

You can use AWS Shield which works for UDP as well. More details at https://aws.amazon.com/shield/

Answer 2

I may be a bit late here but you can use Network ACL to block UDP traffic
