You can enable or disable each protocol (SMTP, POP3, HTTP, ICAP and FTP). If the appliance
is in Transparent Router or Transparent Bridge mode, and the protocol is disabled, traffic for
the protocol passes through the appliance, but is not scanned.
If the appliance is in Explicit Proxy mode, and a protocol is disabled, traffic directed to the
appliance for that protocol is refused. The protocol is blocked at the appliance. In Explicit Proxy
mode, only SMTP, POP3, HTTP, ICAP and FTP traffic is handled by the appliance. All other traffic
is refused.
If, after installation, you do not want to scan any of the types of traffic, you can disable each
protocol from its page. From the menu, select Email | Email Configuration | Protocol
Configuration or Web | Web Configuration
Time Settings
Use this page to set the time and date, and any details for the use of the Network Time Protocol
(NTP). NTP synchronizes timekeeping among devices in a network. Some Internet Service
Providers (ISPs) provide a timekeeping service. For more information about NTP, see RFC 1305
at
www.apps.ietf.org/rfc/rfc1305.html
,
www.ntp.org
or
www.ntp.isc.org
The appliance can synchronize its time settings to other devices, keeping its own logs, reports
and schedules accurate. Because NTP messages are not sent often, they do not noticeably
affect the appliances performance.
