I have 6 computers in a LAN and do some gaming with friends. All of them have Mint 18.3 64-bit, but of course have some different hardware. We play games offline with custom IP addresses like: 10.0.0.1 10.0.0.2 10.0.0.3 etc So I'll host the game on one and everyone will join the game. But its strange that some games won't see the host in the browser. Most games have a direct connect-to-IP option or command, like... Source Engine: connect 10.0.0.1 Unreal Engine: open 10.0.0.1 The problem is, some Linux boxes refuse to see the host in browser and some games do not have an available console or command to connect-to-IP: Titan Quest MX vs ATV Tony Hawk Pro Skater 3 Battlefield 2 Its totally strange because some do see the host and others don't. Are there any suggestions on what I can do to see why some do not see the host in browser? I don't think its Wine because I've had success with it and native games. All the computers are connected to two switches and can easily join other games like: Insurgency Left4Dead 2 The Ship Synergy Half-Life 2 Deathmatch Counter-Strike Source Alien Swarm So I know they are all connected and can ping eachother. I even turn off the firewall with: ufw disable I'm kinda stumped at this point and would love to revive some of these games for LAN gaming.
