Netmail Encrypt uses HTTPS on port 444 for Administration and HTTPS on port 445 for User Administration. These ports need not be opened in your external firewall, since the services are used only from within your organization. However, you may need to modify proxy servers to allow the ports. Also, port 902/903 is used to access the console for the virtual servers. If necessary, this port may also need to be made accessible.
