16.1.1 What You Can Do in the Remote Management Screens
• Use the WWW screen ( Section 16.2 on page 171 ) to configure through which interface(s) and
from which IP address(es) users can use HTTP to manage the ZyXEL Device.
• Use the Telnet screen ( Section 16.3 on page 171 ) to configure through which interface(s) and
from which IP address(es) users can use Telnet to manage the ZyXEL Device.
• Use the FTP screen ( Section 16.4 on page 172 ) to configure through which interface(s) and from
which IP address(es) users can use FTP to access the ZyXEL Device.
• Your ZyXEL Device can act as an SNMP agent, which allows a manager station to manage and
monitor the ZyXEL Device through the network. Use the SNMP screen (see Section 16.5 on page
173 ) to configure through which interface(s) and from which IP address(es) users can use SNMP
to access the ZyXEL Device.
• Use the DNS screen ( Section 16.6 on page 176 ) to configure through which interface(s) and
from which IP address(es) users can send DNS queries to the ZyXEL Device.
• Use the ICMP screen ( Section 16.7 on page 177 ) to set whether or not your ZyXEL Device will
respond to pings and probes for services that you have not made available.
16.1.2 What You Need to Know About Remote Management
Remote Management Limitations
Remote management does not work when:
• You have not enabled that service on the interface in the corresponding remote management
screen.
• You have disabled that service in one of the remote management screens.
• The IP address in the
Secured Client IP Address field does not match the client IP address. If
it does not match, the ZyXEL Device 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.
Remote Management and NAT
When NAT is enabled:
• Use the ZyXEL Device’s WAN IP address when configuring from the WAN.
• Use the ZyXEL Device’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
ZyXEL Device 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.
