Access License Manager through a firewall or proxy server
The BlueZone License Manager allows the unlimited distribution of BlueZone emulation clients, making it ideal for public Internet use. When using BlueZone clients connect to hosts over the Internet, the License Manager and the BlueZone client must be able to communicate, even when firewalls or proxy servers are in place. This communication takes place over TCP/IP port 8421.
Note
The TCP port used by the License Manager can be changed to another port such as port 80. Refer to Changing the listening port for more information.
These settings must be configured in the firewall or proxy server to allow the packets to be exchanged between BlueZone and the License Manager. If this configuration is not in place, BlueZone clients receive an "unable to license" error.
