Range of ports used to connect to Solidworks License Server

We have some problems to configure our firewall in order to authorize client machine to access the License Server.

We already authorized solidworks traffic using destination ports: 25734 - 25735 (as recommended), but we observed connections using ports 1206/1205.

Can some one help me to specify the range of ports used by solidworks to connect to the license server.

Thank you in advance.

During activation of the license server, the option "A firewall is in use on this server" should be checked if you are using a firewall with exceptions. This option sets the outbound ports to be static. If it is unchecked, it randomizes the outbound ports.

Otherwise, it only needs TCP 25734 and 25735 to be open.
