I cannot launch Structural Designer when connecting over a VPN. What changes can I make to resolve this?
QuestionWhen I try to launch Structural Designer when connecting across a VPN, the License Manager launches instead, displaying errors. This issue does not occur when connecting over my local network. What changes can I make to resolve this?
AnswerWhen attempting to use Structural Designer across a VPN, connection issues between the server and client machines may occur, preventing Structural Designer from launching.
A common cause of this can be the firewall on the server and/or the client machine(s) blocking the License Service and possibly Tedds/Structural Designer due to IP packet encryption across the VPN.
ExclusionsTo start with, create an exclusion on the server for the following file:
- C:\Program Files (x86)\Common Files\SafeNet Sentinel\Sentinel RMS License Manager\WinNT\lservnt.exe
If the issue persist, create exclusions for the following files on the client machine.
- C:\Program Files (x86)\Common Files\Tekla\Structural\Licensing\LicenseManager.exe
- C:\Program Files\Tekla\Structural\Structural Designer 2017\TSD.exe
If you wish to create specific port rules then please be aware that the client machine communicates with the server using UDP ANY PORT which is received by the server on UDP PORT 5093.
From the server, traffic is sent from UDP PORT 5093 which is received by the client on UDP ANY PORT.
