Adding Firewall Exceptions for the License Server
If the license server has a firewall enabled, it is likely that attempts from clients to connect to it will be blocked. If you do not need to enforce security at the machine level on your license server, you can disable your firewall to rule it out as a possible cause of issues. Otherwise, you can add exceptions to its rules to allow clients to connect to it.
There are two approaches to allowing clients to connect to the license server through the firewall:
- Adding firewall exceptions for the license server executable files: lmgrd and toonboom.
- Setting up your license server to use specific ports, and adding firewall exceptions for these ports.
While the default Windows firewall supports both methods, the default macOS firewall only supports adding exceptions for specific executable files, and the default GNU/Linux firewall only supports adding exceptions for specific ports.
To configure your license server to use specific ports, see Configuring a License Server Manually.
- If you add exceptions to the firewall for the license server binaries, you will need to add new exceptions for the latest version of the product every time you upgrade the version of the product.
- If you do not configure your license server to use specific ports, lmgrd will use the first available port starting from port 27000 and toonboom will use the first available port starting from port 53000.
