Not displaying in LAN tab.

I am planning to use a computer as a dedicated box to host some servers at this local lan im going to.
I have setup different links, all without different ip’s - I’m trying to run 8 servers…

The thing is, the first servers, the ports of these:

The 5 servers above display fine, but any ports above 27020 do not show up in the lan tab (they dont need to be on the internet).
I can still connect to these via joining through console (connect LOCALIPHERE:27021)
and this works fine. But ofcourse this is an inconvience and I would much rather them all display in the lan tab.
Thanks in advance

The steam browser must not look for games outside of that port range. Try some copy-pasta
