Bigip F5 ve aws edition

https://support.f5.com/kb/en-us/products/big-iq-cloud/manuals/product/bigiq-and-amazon-ec2-setup-getting-started-4-1-0/2.html

Important: The allow-all-traffic security group is critically important for successful operation of the BIG-IP VE on Amazon EC2.

Default bigip ve aws instance works with a different security group name but it seems when bigiq enters the scene that name must be match to allow-all-traffic name otherwise bigiq does not function properly it seems. I could not make it work with different name.

As soon as i set the security group name to allow-all-traffic with the same rules on url example above bigiq and aws and ltm ve instance starts working together?

I try same rules with a different security group name and bigiq + aws connector and instance connection failed with the same rules all accept incoming+outgoing? so it seems that sepecific name applies to function properly?
