BR500 VPN router firmware/user interface port forward missing features

Firmware V5.10.0.3

The old FVS338 had all of the below features and worked great.  I'm surprised and very disappointed they are missing from the BR500.

Custom services are always enabled unless deleted.  An enable/disable check box on each service would be very useful.  Currently you have to delete the custom service to disable and create the custom service from scratch to enable.  This extremely inconvenient.

There is a severe security problem with port forwarding custom services.  Open ports are exposed to the whole world.  The ability to limit port exposure to a specific external IP or a range of specific IPs would solve this security problem.  It is extremely important to implement this safeguard.
