Use the Server Port value from settings.ini.

Pull the port value from settings.ini, to allow broadcasting of several instances on the same IP.

Rather than keeping the entire cInifile instance in memory, you should read the port value from it in the Initialize() method and use that value instead. This will also allow you to gracefully handle non-existent settings.ini (at which point you should just use the default port value)
