Can not get UDP Port 3478 to NAT

I’m setting up a Unifi controller on Windows Server 2012R2. Using a Microtik router. I setup NAT to forward TCP 8080 and UPD 3478 from the gateway interface to a the server IP

When I check with Open Port Check Tool, 8080 works 3478 does not. I can not figure it out both NAT rules look correct.

Can anyone assist? Thanks.
