You can set the maximum number of friends connecting to your machine concurrently. The default max is 20. Remember, for every connection, you will be sharing bandwidth. For example, if the first connection was set at 30mbps and you have 5 friends connected, each friend will only get a 6mbps stream, which will be pretty low quality in fast action games. If you're going to increase it beyond 20, please keep in mind you need to have A LOT of upload bandwidth for a good experience for each user.
