No License found with LAN. License found with WLAN.

Hello,

i use Cadence Allegro 17.4 and everything is up to date. License manager version is 11.14.1.0.

When i connect with VPN and WLAN frome home, the license will be found.

When i connect with VPN and LAN from home, no license will be found.

If i connect with LAN at company, license will be found. WLAN too.

I work with a local dongle on my notebook.

Follow information is shown at home, when it doesnt work.

"Retrieval ao 'Allegro_performance' license failed: 'ERROR (LMF-13015): Licnese call failed for feature PCB_design_studi. The license server search path is defined as <none>. The FLEXnet error message is as follow, FLEXnet ERROR (-15,234, 0): Cannnot connect to license server system.

Run 'lic_error LMF-13015' for more information'. Report the licenses in use log via the menu item File->Viewlog: License_use.log.

Notebook System is Windows 10.

VPN is CheckPoint.

Any idea, where the problem could be?

Thanks.
