18.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Remote Management Limitations
Remote management over LAN or WAN will not work when:
1
A filter in SMT menu 3.1 (LAN) or in menu 11.5 (WAN) is applied to block a Telnet,
FTP or Web service.
2
You have disabled that service in one of the remote management screens.
3
The IP address in the Secured Client IP field does not match the client IP
address. If it does not match, the WiMAX Modem will disconnect the session
immediately.
4
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.
Remote Management and NAT
When NAT is enabled:
• Use the WiMAX Modem’s WAN IP address when configuring from the WAN.
• Use the WiMAX Modem’s LAN IP address when configuring from the LAN.
System Timeout
There is a default system management idle timeout of five minutes (three
hundred seconds). The WiMAX Modem 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. You can
change the timeout period in the Maintenance > System > General screen.
