ECURITY

The Mini Broadband Router includes the facility to manage it from a remote

location. The unit can also be sent a ping message from a remote location.

Figure 63: System Security

The following items are displayed on this page:

◆

Remote Management

— Denies or allows management access to the

Mini Broadband Router through the WAN interface. (Default: Deny)

◆

Ping from WAN Filter

— When enabled, the Mini Broadband Router

does not respond to ping packets received on the WAN port.

(Default: Disable)

◆

Stateful Packet Inspection (SPI)

— The Stateful Packet Inspection

(SPI) firewall protects your network and computers against attacks and

intrusions. A stateful packet firewall looks at packet contents to check if

the traffic may involve some type of security risk. (Default: Enable)
