Cisco 678 question

[Miles Beck]

Does anyone know the command to delete a port forward to a specific range?

I've been using the following command to delete a range and it is not working.

set nat entry delete 10.0.0.2 6881-6999 xx.xx.xx.xxx 6881-6999 tcp

The xx address is my external address for my router, which I have
removed for this email.

Removing a specific port worked but I cannot get the range removed.

Thanks,

-Miles
