open port to multiple IP's

Question

I am looking to open a port to a EC2 Instance from multiple ip's. Rather than creating a rule for each IP address is there any other options. I have tried creating a prefix list and added a list of IP's there but when i try apply prefix list in the secuurity group i get an error The maximum number of rules per security group has been reached.

Answer

May be you've reached the [rules limit per Security Group](https://docs.aws.amazon.com/vpc/latest/userguide/amazon-vpc-limits.html#vpc-limits-security-groups)? If so, you can request [limit increase](https://console.aws.amazon.com/servicequotas/home/services/vpc/quotas/L-0EA8095F) through AWS support case.
