At the moment I am trying to port forward for Minecraft Bedrock (PE) server, however, when I go into Virtual Server Setup, my router asks me for a 'Custom Service/Application.' I have no idea what this should be, as far as I am aware the port I am supposed to be forwarding is 19132 UDP. I'm using a Sagemcom f@st 3864V2. If I try to use port triggering, it doesn't ask me for an IP address, so I'm not sure if that is what I should be using? Either way, I have looked online for results and I have tried every 'Application' suggested. Any way I can get this to work??
In port forwarding click the custom service radio button and then add the specific ports you need.
I just had a look on my router and that field is for a name to give your custom configuration.
Note the I get an error 9003 no matter what name I give it. But that could be just my setup because I don't actually have an internet connection on that device (I just use it for testing) and therefore nothing in my "User Interface" dropdown list.
