Stop turning threads into shitholes! This thread was closed way too late! From the beginning of post 4, eftertanke misunderstood. Then people followed.
Summary: Since you are on a LAN with no internet, there is no need to do anything because the server cannot access the masterserver. Your ports probably aren't forwarded either (Ronald mentioned that). In case you did need anything,
-mlocalhost
would do (samsat mentioned that) in your servercmdline.txt OR in your server launcher, usually server.bat.
I quoted a section of the docs that talked about -mlocalhost, but it is true that you did not know what to look for, and we all know how great the docs are. It's normal to post links to the documentation, hoping that people understand, but common courtesy usually kicks in and some of us provide alternative descriptions. I'm just scared of patronizing.
