You can control your network device activities by configuring your device to filter out traffic on specific network connections. You can disable protocols, such as FTP, HTTP, and Telnet. Port filtering on devices disables network connections individually. When a port is closed, a device does not respond to traffic on the specified port even if the corresponding network application is enabled. We recommend that you close any ports that you do not plan to use during standard operation.
- From the Embedded Web Server, click Settings > Network/Ports > TCP/IP > TCP/IP Port Access.
- Enable the access to the TCP/IP ports.
- Click Save. Note: For more information on each port, contact your system administrator.
