Paragon neo: TCP Ports / Communications
The following TCP ports are required to be open on Paragon-Neo to enable remote operation:
Port | TCP Port | Requirement | Description |
|---|---|---|---|
HTTP | 80 | Mandatory
| HTTP / HTTPS access to Paragon-neo for GUI, page navigation, and remote control commands. One or both of ports 80 and 443 must be open. Websockets also uses these ports for the Paragon-neo to asynchronously update the GUI. |
HTTPS | 443 | ||
SMB | 445 | Optional | Access to the Paragon-neo instrument file share. Allows upload/download of files via explorer or shared/mapped drives. |
| 4502, 4503 | No longer used. | Earlier versions of CAT and PFV used port 4502 and/or 4503 for communication between browser and CAT/PFV. Recent versions of CAT and PFV use ports 80 and 443. Ports 4502 and 4503 may be blocked by a firewall or network security settings. This may cause CAT/PFV to not display in the browser correctly, hang or show errors. |
The status of the Paragon-neo websocket port can be tested by navigating to the following page (assumes port 80 is accessible) and viewing the “Web Socket Communications” status:
