Enter a name for the application for which you want to
create the rule.
NOTE:
Use these fields to specify the incoming port range.
These are the ports on which the CGNV2 received traffic
from the originating host on the WAN.
Enter the start port number in the first field, and the end
port number in the second field.
To specify only a single port, enter its number in both
fields.
Use these fields to specify the ports to which the
received traffic should be forwarded.
Enter the start port number in the first field. The number
of ports must match that specified in the Public Port
Range, so the CGNV2 completes the second field
automatically.

forward traffic via:
