15.1.2 What You Need To Know About Remote Management
Firewall Rules
When you configure remote management to allow management from any network except the
LAN, you still need to configure a firewall rule to allow access. See Chapter 9 on page 181 for
details on configuring firewall rules.
You can also disable a service on the LAN-Cell by not allowing access for the service/protocol
through any of the LAN-Cell interfaces.
Remote Management Sessions
You may only have one remote management session running at a time. The LAN-Cell
automatically disconnects a remote management session of lower priority when another
remote management session of higher priority starts. The priorities for the different types of
remote management sessions are as follows.
1 Console port
2 SSH
3 Telnet
4 HTTPS and HTTP
Remote management allows you to determine which services/protocols can access which
LAN-Cell interface (if any) from which computers.
Remote Management Limitations
Remote management does not work when:
1 You have not enabled that service on the interface in the corresponding remote
management screen.
2 You have disabled that service in one of the remote management screens.
3 The IP address in the Secure Client IP Address field does not match the client IP
address. If it does not match, the LAN-Cell 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.
5 There is a firewall rule that blocks it.
6 A filter is applied (through the SMT or the commands) to block a Telnet, FTP or Web
service.
System Timeout
There is a default system management idle timeout of five minutes (three hundred seconds).
The LAN-Cell 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 > General screen.
