A firewall prevents unauthorized Internet users from accessing your local network and
computer.
AirTies Firewall has SPI (Stateful Packet Inspection) feature. SPI monitors the protocol and
packet addresses being received to determine if the information should be passed through
the firewall to the connected computers. Internet addresses that are a source of malicious
attacks are permanently blocked from accessing your network.
You can also limit or block the Internet access of any local user by defining advanced rules
for Internet access.
The following sections describe the submenus under the FIREWALL menu of the Web
interface.
