The "Max" displayed in the /lusers data does not represent a limit to the number of users that can connect. It simply shows the max users (+ 1) that have connected to that server at any one time. I'm not sure whether that number has any significance in the operation of the server or if it is just for informational purposes. The server should automatically update that value when more users connect. If you haven't had 25 users on your server yet, that may just be the default value that the server comes programmed with.
