# 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).
