HELP NEEDED--How to set up port forwarding: Apple AirPort Extreme

[nycbassguy@gmail.com]

Hi everyone, hoping to get some help here. Joined JK a few weeks ago and had limited success with audio. I've combed thru every available resource i can find on this site and others, but i'm still having difficulty setting up port forwarding on my airport to solve the 'no audio' issues i always run into. also getting the warning that my network changes packets/port numbers when i boot up the app. here's what i have so far:

GEAR
iMac running 10.12.6
Apogee ONE interface
Apple Airport Extreme (w/Ethernet)

-- on PortChecker, the ISPs match so that's 👍
-- Router Mode: DHCP and NAT
-- Port Settings: I set up an IPv4 port mapping setting and named it JK (duh)
Public UDP Ports: 12000
Public TCP Ports: 12000
Private IP Address: 10.0.1.201
Private UDP Ports: 12000
Private TCP Ports: 12000

-- under Network Options i have NAT Port Mapping Protocol enabled
-- the 'Enable default host at:' field is not checked and no value is entered

One of my questions is how to enable a RANGE of ports on the airport, i.e. 12000-12010


Anything I need to do, besides get a JOB????

Thanks in advance--
