Configuration of the Log/Log Settings for SNMP
Trap messages are generated only for the categories that alert messages are normally
sent, i.e. attacks, system errors, blocked web sites. If none of the categories is selected
on the Log Settings page, then none of the trap messages are sent out.
Configuration of the Service and Rules Pages
By default, the SonicWALL appliance responds only to SNMP Get messages received on
its LAN interface. Appropriate rules must be set up in the SonicWALL to allow SNMP
traffic into the trusted network. SNMP trap messages may be sent via the LAN, WAN,
or DMZ interface.
If your SNMP management system supports discovery, the SNMP agent should
automatically discover the SonicWALL appliance on the network. Otherwise, you need
to add the SonicWALL appliance to the list of SNMP manageable devices on the SNMP
management system.
Remote Management
All SonicWALLs include a Management Security Association (SA) for secure
remote management. The Management SA does not permit access to remote
network resources.
Note: If you have enabled VPN on your SonicWALL, the SonicWALL may be managed
remotely using a Management SA or with a VPN SA.
To enable secure remote management, click Access on the left side of the browser
window, and click the Management tab at the top of the browser window. Then select
