Port – port range

Select a port or port range to view or edit its properties.

Name of the object Name of the service used.
This field is grayed out and cannot be modified.
Port Number of the port associated with the selected service.
Port range By selecting this option, you will assign a port range to the selected service and enable the two checkboxes below it.
From If the Port range checkbox has been selected, this field will be enabled. It corresponds to the first port included in the selected port range.
Up to If the Port range checkbox has been selected, this field will be enabled. It corresponds to the last port included in the selected port range.
Protocol Select the IP protocol that your service uses:
  • TCP: Transmission Control Protocol. Transport protocol operating in connected mode and made up of three phases: establishment of the connection, data transfer, end of the connection.
  • UDP: User Datagram Protocol. This protocol allows data to be transferred easily between two entities, each of them having been defined by an IP address and a port number.
  • SCTP: the Stream Control Transmission Protocol is defined in RFC 4960 (an introduction is provided in RFC 3286). As a transport protocol, SCTP is in a certain way equivalent to TCP or UDP. While TCP is traffic-oriented, (the sequence of bytes contained in a packet does not have a conceptual beginning or end, but belongs to the stream of traffic that makes up the connection), SCTP — like UDP — is message-oriented (it sends messages in a traffic stream with a beginning and an end, which can be segmented over several packets).
  • Any protocol: The selected service can use any IP protocol.
Comments Description of the selected port or port range.

If you wish to add a port that can be used for UDP and TCP traffic:

  1. Create a TCP-based port object first of all (e.g.: MyTCPport = TCP/1234),
  2. Create a second port object, this time based on UDP (e.g.: MyUDPport = UDP/1234),
  3. Group both of these objects in a Port group object that you will be able to use in your firewall configuration (e.g.: MyPortGroup incluant MyTCPport and MyUDPport).
