Prestige 660H/HW Series User’s Guide
171 Chapter 15 Remote Management Configuration
• A filter in SMT menu 3.1 (LAN) or in menu 11.5 (WAN) is applied to block a Telnet,
FTP or Web service.
• You have disabled that service in one of the remote management screens.
• The IP address in the Secured Client IP field does not match the client IP address. If it
does not match, the Prestige will disconnect the session immediately.
• There is already another remote management session with an equal or higher priority
running. You may only have one remote management session running at one time.
• There is a firewall rule that blocks it.
15.1.2 Remote Management and NAT
When NAT is enabled:
• Use the Prestige’s WAN IP address when configuring from the WAN.
• Use the Prestige’s LAN IP address when configuring from the LAN.
15.1.3 System Timeout
There is a default system management idle timeout of five minutes (three hundred seconds).
The Prestige automatically logs you out if the management session remains idle for longer
than this timeout period. The management session does not time out when a statistics screen is
polling.
15.2 Telnet
You can configure your Prestige for remote Telnet access as shown next.
Figure 79 Telnet Configuration on a TCP/IP Network
15.3 FTP
You can upload and download Prestige firmware and configuration files using FTP. To use
this feature, your computer must have an FTP client.
