Hi.
I’m having some issues with Steam and LAN connections. I’ve got my session started, no errors there, but Steam/the game is simply not opening the port it says it is and the resolved connection string says it’s using. Here are my steps:
- Start the game (in debug / packaged build - yes, steam is enabled and working)
- I browse to a map to start a server (open map?listen)
- Steam says it’s bound to port 7777.
- I start the Steam LAN session in my game mode’s post initialize components (right place? who knows. It works.)
Resolved connection string from the find session query on another instance of the game returns my lan ip and port 7777 (“192.168.1.3:7777”.) Connecting to that port does not work. And I get nothing listed on port 7777 using netstat -a. Here’s the relevant log lines:

There is nothing in the log about the port closing or the net driver shutting down. Or about a client trying to join. On the client I get:

Anyone have any ideas?
Edit: To note, if I disable steam and use the null online subsystem, it works fine, so it’s not a port or firewall issue.
Edit 2: Still using the steam dev app id (480.) That shouldn’t make a difference on LAN, though?!
