Ports - Xerox WorkCentre 6400 Information Manual

device-initiated operations (like scanning) cannot assume the existence of the tunnel unless a print job (or other
client initiated action) has been previously run since the last boot at either end of the connection.

Please note that there is no ftp port in this list. ftp is only used to export scanned images and to retrieve Scan Job
Templates, and will open port 21 on the remote device. An ftp port is never open on the controller itself.
2.8.2.1. Port 25, SMTP
This unidirectional port is open only when Scan to E-mail or Internet Fax (I-Fax) is exporting images to an SMTP
server, or when email alerts are being transmitted. SMTP messages & images are transmitted to the SMTP server
from the device.
2.8.2.2. Port 53, DNS
Designating a DNS server will allow the device to resolve domain names. This can be configured via the LocalUI or
WebUI.
2.8.2.3. Port 68, DHCP
This port is used only when performing DHCP, and is not open all of the time. To permanently close this port, DHCP
must be explicitly disabled. This is done in User Tools via the Local User Interface or via the TCP/IP page in the
Properties tab on the WebUI.
2.8.2.4. Port 80, HTTP
