Firewall
Expert > Security > Firewall
The WiFi gateway features a built-in firewall that provides protection to your network from unauthorized intrusions from the Internet. The
firewall features four modules which can be enabled or disabled using the switches.
SPI Firewall
Stateful Packet Inspection (SPI) firewall protection means only
packets matching a known active connection will be allowed by
the firewall, and others will be rejected. An SPI firewall goes
beyond stateless filtering and checks an entire packet’s content
rather than only packet headers. This is a security feature to help
distinguish between legitimate packets of information and
potentially harmful packets, and provides greater security for your
network.
DoS Protection
Denial-of-Service (DoS) is a common form of malicious attack
against a network. The WiFi gateway
’
s firewall can protect against
such attacks by filtering unreasonable packets that could flood
and disable network with large amounts of traffic.
WAN Block Ping
When active the WiFi gateway will not answer ping requests from
the Internet. This can increase security as pinging is a common
method used by hackers to test networks.
LAN Block Ping
When active the WiFi gateway will not answer ping requests from
the local network. This can increase security as pinging is a
common method used by hackers to test networks.
