Outgoing network ports for TrueConf solutions<\/h2>\r\n\r\n

TrueConf Server may require outbound ports to enable additional services listed below. All the indicated ports can be closed; they don\u2019t influence video conferencing services operating via TrueConf protocol.<\/p>\r\n\r\n

Please note that these ports affect only the outbound traffic from your corporate network, which means that your corporate communications will stay secure even if outbound ports are opened.<\/p><\/div>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

TrueConf Server Control Panel<\/h2>\r\n\r\n

TrueConf Server Control Panel<\/a> enables administrators to manage the server from any device on the corporate network.<\/p>\r\n\r\n

Please make sure that the firewall of the server allows connection through the port used by TrueConf Server \u0441ontrol panel.<\/p>\r\n\r\n

Web TCP Port (control panel port) and Database TCP Port (database port) are specified during TrueConf Server installation<\/a>. By default the ports are 80<\/b> and 5432<\/b> respectively, however other available ports may also be selected. You can change Web TCP Port<\/a> without reinstalling the server.<\/p>\r\n\r\n

\r\nTo enhance your network security, we recommend enabling HTTPS and closing port 80.\r\n<\/p><\/div>\r\n\r\n

Media data exchange with client applications<\/h2>\r\n\r\n

By default, the exchange of media (audio and video) between the server and client application is delivered through the TCP port 4307<\/b>. But you can change it in the settings of TrueConf Server \u0441ontrol panel (tab Network \u2192 Network Settings<\/strong><\/a>) to another TCP port of your choice. This port is also used for file transfer in chats<\/a>.<\/p>\r\n\r\n

Please note that client applications should be downloaded from the guest page of your server. If you have changed the port value on the server after the installation of client applications, all client applications need to be reconfigured manually to use new server address and port.<\/p>\r\n\r\n

Slideshow<\/h2>\r\n\r\n

Slideshows will be sent to the address and port specified in the External address of TrueConf Server web<\/strong> block of the Web \u2192 Settings<\/strong> section<\/a>. So if HTTPS connection<\/a> has been configured on the server side, an HTTPS port (443<\/b> is selected by default) is used for slideshow<\/a>; otherwise a Web TCP port is used (80<\/b> is selected by default).<\/p>\r\n\r\n

443<\/b> port is also needed for displaying the conference scheduler<\/a> and real-time layout manager<\/a> in TrueConf client applications.<\/p><\/div>\r\n\r\n

Connection between TrueConf Server and a registration server<\/h2>\r\n\r\n

A connection of your TrueConf Server machine to our registration server is established through the TCP port 4310<\/b> after entering a registration key on the registration page of TrueConf Server.<\/p>\r\n\r\n

If the server is behind a firewall, you need to grant access to the Internet through the port 4310<\/b> (proxy is not supported).<\/p>\r\n\r\n

TrueConf Server Free requires a persistent connection to the registration server through the port 4310<\/b>. This port cannot be reassigned. The full version of TrueConf Server does not require this port.<\/p>\r\n\r\n

TrueConf Server Free transmits service information to registration server in order to:<\/p>\r\n\r\n
