LMTools trough reverse proxy

[ddehaan]

Hi everyone!

We have, as many others do, a situation where our teachers are giving remote classes from their home. We have a LMTools license server running in our network, but we're having trouble making it available through our VPN. The program we are using to test this is Inventor 2020..

Our VPN is a Citrix Netscaler and we want to use reverse proxy to connect to the server. We have forewarded the port 2080 and 27000-270009. When we telnet on these ports, we can reach the license server and  when we use a browser session on port 2080 we get the same results as on premise.

But... We're getting a "FlexNet License Finder, Your application was not able to obtain a license because the FlexNet license manager could not determaine where to find the licensing data it needs".

Does anyone know if reverse proxy is even possible with FlexNet?

Thanks in advance for the help!

Kind regards,
Dennis de Haan

Could be a timeout problem. Have a look at this:

Hi Gunnar,

Already tried it with the 3000000 value, but not with 10000000. Sadly, that both options did not work 😞

Check if there's a service listening on ports 2080 and 27000. Try this both in house and through vpn. Try both with servername and ip.

http://<servername>:2080 and http://<servername>:27000

The response should be a string like Wê-60Wê-60Wê-60

Hi !

Using IPV4 or IPV6 ?

Hi everyone!

Thank You all for helping, but unfortunately none of the suggested tips worked. 

Seems that it's simply not supported 🙂

We ended up moving the server to another VLAN that could be accessed both on premise and via VPN, so our problem has been resolved 🙂

Thank You all for helping and stay safe 🙂

Kind regards,
