7.5.5 UDP Path Options

Remote port

Selecting an option from the drop-down sets Value to the standard port for the selected protocol.

To configure other port values, select OTHER and type the port in the Value field.

Local port

The default value (Auto Selected) lets the TCP/IP transport determine which local port to use. To specify a specific port, clear this option and enter the local port number in the Value field.

Visible addressing

This option is available only if IP address or domain name on the TCP/UDP Path Options dialog box contains an asterisk (*).

Select this option to pass the IP address of each received UDP datagram to the application. You should select this option only if your application is designed to process this information.When this option cleared (the default), the TCP/IP Transport removes and stores the IP address from any received datagram and passes only the data itself to the application. When it receives a response from the application, the TCP/IP transport automatically adds the stored IP address at the beginning of the data before sending it out. The TCP/IP Transport handles the datagrams on a first-in/first-out basis. In other words, if it receives a datagram from one host and then receives a datagram from another host, it assumes that the first response from the application should be sent to the first host. If the application does not respond to the first datagram but does respond to the second, that response will be sent to the first host rather than the second.
