How to Establish a VPN with Us

There could come a time when you need to establish a VPN with us. Typically a VPN will be used for licensing purposes, i.e. providing access to a license on your own corporate network.

In order to expedite the VPN setup, please take a look at our VPN questionnaire.

Once the VPN tunnel has been established, we'll want to work with your license server administrator to verify connectivity and configure the license server. We strongly recommend that you use the standard FlexLM licensing TCP ports. If you don't, you will need to set up port forwarding for those default ports. For reference ANSYS uses ports 1055, 2325, 2326, and 27000. Not using the standard ports, could delay your licensing setup.

If you have any questions about default ports, please reach out to us.

Happy VPN'ing!
