Specifying a fixed port for MW licensing through a firewall
Describes how to specify a fixed port for use by the license server through a firewall.
Two ports must be open for MW licensing to function correctly through a firewall. The first port is used by the FLEXnet license server manager, and defaults to port number 27000. The second port is used by the vendor daemon rtirmw.exe, and is dynamically allocated by default. If the allocated port is blocked by the firewall, Error -96 is issued, and the vendor daemon fails.
To ensure that an open port is always available for the vendor daemon, you can hard-code the second port number in the license file. You do not need to generate a new license file or have the modified license file digitally re-signed after hard-coding the port number.
To hard-code the port number in the license file, open the license file in an editor and find the VENDOR line, which for MW generally looks like this:
Append the port number as follows:
VENDOR rtirmw PORT=28500
FLEXnet normally uses ports 27000-27009. It is best to assign a port number greater than 27000, and to make the port number high enough to avoid a conflict with any other installed license servers.
