I followed the tutorial, some forum posts and some videos but I feel it's impossible to me to create a server, so I need to ask here:
First of all I have the legal game and the verification successfull. I have downloaded the files and put them where it says in the tutorial (and even on more places trying to make it work). I created the folder "gameserver/T6" in C disk and I pasted there like everything:
I created the servers online and put the key in the start server bat files:

I believe I did everything I can with the port forwading thing:

I hope at least one of all of those is correct. I have internet through wifi on the laptop and the IP is the .106 one.
I created a million rules in firewall, both inbound and outbound and both tcp and udp just in case
I have even additional rules containing ports separately or whatever but seems doesn't matter.
I have put the localappdata folder files in the AppData/Plutonium/... place. I also have plutonium.exe and it's folder copied in the gameserver/T6 folder to try. I have the start_server.bat both, in this folder but also in the steam/common/BO2 folder.
I tryed running the server from both places. Tho, I always get the heartbeat thing correct, so the server is actually working. The problem might come with the port thing, but I don't know what else I can try. I never see my server in Server Browser, despite I think I followed all instructions and several tutorials.
Maybe things changed in this last few years and they are outdated. I hope anyone can help me, I will be extremely thankful. If you need any other screenshot just ask me, there's no problem.
