ser’s Guide
• Your Device can act as an SNMP agent, which allows a manager station to manage and monitor
the Device through the network. Use the SNMP screen (see Section 24.5 on page 199 ) to
configure through which interface(s) and from which IP address(es) users can use SNMP to
access the Device.
• Use the DNS screen ( Section 24.6 on page 201 ) to configure through which interface(s) and
from which IP address(es) users can send DNS queries to the Device.
• Use the ICMP screen ( Section 24.7 on page 202 ) to set whether or not your Device will respond
to pings and probes for services that you have not made available.
• Use the SSH screen ( Section 24.8 on page 203 ) to configure through which interface(s) and from
which IP address(es) users can use SSH to manage the Device.
24.1.2 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 Device will disconnect the session immediately.
• There is a firewall rule that blocks it.
Remote Management and NAT
When NAT is enabled:
• Use the Device’s WAN IP address when configuring from the WAN.
• Use the Device’s LAN IP address when configuring from the LAN.
