By knowing the application's protocol for which you write the rules for :P |

For example, if I write some rule that applies to traffic generated by a |

web server and web browsers, that's TCP. If I write rules that apply to |

an online game's matchmaking and game discovery browser, that's UDP (but |

depends on the game). So you have to research a bit to see if the |

application uses TCP or UDP. |
