However, for EC2 Linux instances you'll need to enable IP forwarding by disabling Source/Destination Check for the instance in addition to setting net.ipv4.ip_forward=1 for the VM.
Also EC2 uses layered security, so you may have OS level packet filter, then NACLs (if used - stateless), finally Security Groups (stateful).
