ipv6 – How do I port forward a Minecraft server on Google Fiber?

I need to port forward the following ports:

IPv4: 19132
IPv6: 19133
IPv4: 34578
IPv6: 57597

all on TCP & UDP.

I need to do this because I want to port forward a Dedicated Minecraft Bedrock Server, following instructions here.

I did a quick Google search and found this Google article, but I’m kind of confused – there are so many options!

I did this in the Fiber setup, but it didn’t seem to work…

I port forwarded on the device of my internet’s name, with Universal Plug and Play set to on, choosing the IP address of my Ubuntu server (the IP with letters and colon; the one that is very long), forwarding a single port 19132->19133 (I’m not doing the second port yet), with protocol TCP & UDP.

I think I’m getting the ports wrong (IPv4 or IPv6?), or maybe the “Single port” selection, but I have no idea!

What am I doing wrong?

Appreciate the help!
