Bridge Mode Firewall Configuration Settings
The
firewall
functionality on a bridge interface can be enabled using the "Enable Firewall" option. The
bridge firewall rules can be configured, enabled, or disabled while using the firewall configuration
window which can be opened with the "Configure" button.
Firewall entries can be specified by following the criteria below:
Access the interface (WLAN or LAN) where filtering of the incoming or passing-through
packets are processed.
Filter the IP type sets for the particular Layer 3 protocol type (ICMP, TCP, and UDP).
o
Source IP/mask is the source IP of the packet (specified within the packet header),
which is usually the IP of the host system which sends the packets.
o
Source port of the TCP/UDP packet (specified within the packet header), which is
usually the port of the host system application which sends the packets.
Destination IP/mask
is the destination IP of the packet (specified within the packet header), which is
usually the IP of the system which the packet is addressed to.
Destination Port
is the destination port of the TCP/UDP packet (specified within the packet header),
which is usually the port of the host system application in which the packet is addressed to.
Comments
are the informal field of a particular firewall entry. Only a few words about the purpose for a
particular firewall entry are generally saved.
On
flag enables or disables the effect of the particular firewall entry. All the added firewall entries are
saved in a system configuration file, however only the enabled firewall entries will be active during the
system operation.
New firewall entries can be saved by activating the
‘Apply’ button or can be discarded by activating the
‘Cancel’ button in the firewall configuration window. All the active firewall entries are stored in the
FIREWALL chain of the editable filtering table while the device is operating in bridge mode. Click the
‘Apply Setting and Save Changes’ button to save the changes made in the ‘Network’ page.
