open port to multiple IP's

0

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.

May be you've reached the rules limit per Security Group? If so, you can request limit increase through AWS support case.

    no, i have an existing instance with a security group that has 30+ rules ...the new instance has a only 5 rules and the prefix list has only 10 IP's listed...don't understand why you cant add a port and comma separate the ip's in one rule
