I have a situation where we have a 2022 R1 license server for our Academic Ansys license. The license server is Windows 2019 and to clients on the local area network everything works. We have clients on another network and have all the firewall rules in place for port 1055, 1056 and 2325. We have created firewall exceptions on the Windows 2019 server to allow the TCP ports as well as allowing the programs:

ansyscl.exe

ansysli_server.exe

ansysli_monitor.exe

ansyslmd.exe

lmgrd.exe

Our remote clients are both on Windows as well as Linux. The windows clients will open an older version of Ansys such as 2021 but it won't license 2022 R1. The network team says the packet goes to the license server but then it times out and resets the connection. The Linux clients simply don't work at. Anyone ran into a situation like this and discovered the solution?

Hi tfoley Perhaps specify the vendor port (1056 in your case) rather than the lmgrd port (1055 in your case) in the ansyslmd.ini in the remote clients ansyslmd.ini file:
SERVER=1056@LicenseServerName
This will not allow the clients to perform license status (lmstat) but, suspect it will resolve your issue.

We tried this and got this error:
Error getting status: invalid return data from license server system (-12,16). Let me add that at the beginning of my license file I have:
SERVER ENG-FS2 "mac address" 1055
VENDOR ansyslmd PORT=1056
USE_SERVER

Hi tfoley My colleague will be contacting you directly regarding this issue.
thanks

I finally got this working. I was advised to create these two new environmental variables:

ANSYSCL_TIMEOUT_CONNECT=40
ANSYSCL_TIMEOUT_RESPONSE=90

Once we did this it started working.
