AWS ElasticLoad Balancer Inbound traffic security group rules, allow only my ip? [on hold]

My objective:

To make my AWS Elastic Load Balancer hittable by only traffic from my ip.

What I have tried:

• created a security group in EC2 security groups


• set an inbound rule that allows all traffic from my ip [all, all, all, /32]


• assigned this ELB the newly created security group


• attempted to hit the elb from an ip outside myoffice

The results:

All traffic, even from ips other than mine could still hit my ELB (and thus get through to my app servers).

What am I doing wrong? How can I block inbound traffic to my ELB (and the EC2 instances behind it)?
