Specifically, UDP doesn't provide sequencing of the packets that the data arrives in. This means that the application program that uses UDP must be able to make sure that the entire message has arrived and is in the right order. Network applications that want to save processing time because they have very small data units to exchange (and therefore very little message reassembling to do) may prefer UDP to TCP.
Example:
ID | Trigger Port | Trigger | Public Port | Public | Comment | |

The virtual server option allows you to define port number on your router for redirection to an internal LAN IP address. This feature is useful for hosting online services such as FTP or Web servers.
Example:
ID | Server IP | Mapping Port | Type | Comment |

1 | 192.168.0.20 | 80 | TCP | Web Server |
