ASUS RT-AC5300 Port Triggering

[Dinglestains]

I can't get port triggering to work with the ASUSWRT-Merlin firmware. I have it set to trigger on the Xbox Live port (3074), but it doesn't open when my Xbox attempts to use it. I've tried disabling UPnP, but that didn't seem to help. Does anyone have this working or have any suggestions? I would just forward the ports, but I have multiple Xbox's that use this port.

Just use UPNP, no need for port triggering.

I've tried using UPnP, but it never seems to work properly with multiple consoles on the same network. It works great for one console, but the other always shows a "Moderate" NAT type meaning port 3074 isn't open for that IP address.
