FIREWALL Settings
A firewall prevents unauthorised Internet users from accessing your
local network and your computer.
AirTies Firewall has a 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 on your network. The 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.
Firewall is activated by default.
The following sections describe the submenus under the FIREWALL
menu of the web interface.
Access Control
You can allow or block Internet access for any computer on your
local network using the Access Control feature. These access
restrictions can be based on IP address as well as MAC address.
Access Control is enabled by default.
To define a new access rule, click "New".
On the page that appears:
1. Enter a name for the access rule you would like to define in the
"Rule Name" field. Choose a name that is easy to remember.
2. If VLAN is implemented then select the LAN or WAN interface,
otherwise take the defaults.
3. In the "SELECT CLIENT" section you can enter the IP or MAC
addresses of the clients whose access you would like to restrict
with this rule.
4. Access control can be defined based on local IP or MAC address
(uniquely identifies the network adapter of the device). If an
access rule is defined by MAC address, the rule defined for the
device will be valid even if the local IP address changes.
5. It is possible to enter the MAC or IP addresses individually or
choose them from the list of client devices in the local network.
6. Enter the MAC address of the device you would like to restrict
traffic from in "New MAC Address" or IP address of the device
in the "New IP address range" field. For a single IP address,
enter the same value in the two boxes that define the range.
