Firewall
Expert > Security > Firewall
The 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 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 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 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.
