Selecting an Alternative Service Port
The default listening port for FTP services is 21. Administrators whose network secu-
rity policy requires the use of nonstandard ports for servers may want to change this
default.
To select an alternative service port for FTP services:
1. On the left menu, click FTP. The FTP screen appears.
2. In the Service Port section, type the desired port in the FTP listening service
port(s) field.
3. Click Save. A message displays informing you that the appliance must reboot in
order for this change to take effect.
4. Click OK to dismiss the message. A countdown screen appears and counts down
from 3 minutes while the appliance is rebooting. When the appliance has
rebooted, the Web console login screen appears.
5. Log on to the Web console to make any further changes.
Tip: If you are changing the FTP service port as a security measure against hackers,
Trend Micro recommends that you use the less commonly used ports (those above
6000).
