Number of ports required for a floating license

The port number cannot repeat with your existing port number. For example, I would suggest you any random port number like 8888.

Thank you for your reply.

Is it sufficient to have just one open port?

Example: 1800

Thank you for your reply.

I have confirmed that the ports are open.

Since the "Current license" could not be recognized using a single port,I opened three ports.

SERVER　servername　 mac address　10000

VENDOR alterad C:\FLEXlm\alterad.exe　PORT=10001

VENDOR mgcld C:\FLEXlm\mgcld.exe　PORT=10002

I have confirmed that the ports are open.

Since the "Current license" was not recognized with just one port,

I opened three ports.

The "Current license" was successfully recognized, allowing Quartus to operate normally

and enabling the compilation to start.

I plan to continue using it this way, but do you happen to know why more than one port was required?

I would appreciate your response.

Thank you for your reply.

I tried using ports such as 1800 and 58888, but the license was still not recognized.

However, the license is recognized and Quartus works correctly when using three ports, so I will continue using it this way.

I am incredibly grateful for your continuous support and the detailed answers you have provided for my consultations.
