How do I disallow weapons like BFG or Rocket Launcher on my server? I want to play DM against bots, I know how to setup server, spawn bots and so on, but I want to disallow these weapons, Is this possible?

You'll have to use either DECORATE (replace the RL and BFG actors with dummy ones) or MAPINFO (ReplaceActor property) in a custom WAD to do this. As far as I know for built-in functionalities, you can only control which weapons you can have in the Last Man Standing gamemode, with the lms_* variables.
