16.1.1 What You Can Do in the Remote Management Screens
• Use the WWW screen ( Section 16.2 on page 183 ) 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 184 ) 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 185 ) 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 186 ) to configure through which interface(s)
and from which IP address(es) users can use SNMP to access the ZyXEL Device.

ZyXEL Device.
• Use the ICMP screen ( Section 16.7 on page 189 ) 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.
