Amazon EC2 inbound filter for private IP

Amazon EC2 inbound filter for private IP

I have two ec2 instaces created in Amazon cloud, one with public
IP(Elastic IP), and another with only private IP 172.31.5.151. Then, set
security group to the instance with public IP to limit https inbound
access like 172.31.5.151/32
But it doesn't work. When I chanage the https inbound filter to 0.0.0.0/0,
then everything works fine. The question is: how to set inbound filter for
a private IP?
Thanks.
