segment where device resides. If the device IP settings and administrator PC (which is
connected to the device in wired or wireless way) IP settings will use different address
space, the device will become unreachable.
Netmask:
This is a value which when expanded into binary provides a mapping to define
which portions of IP address groups can be classified as host devices and network
devices. Netmask defines the address space of the network segment where device
resides. 255.255.255.0 (or /24) Netmask is commonly used among many C Class IP
networks.
Gateway IP:
Typically, this is the IP address of the host router which provides the point of
connection to the internet. This can be a DSL modem, Cable modem, or a WISP gateway
router. Device will direct the packets of data to the gateway if the destination host is not
within the local network. Gateway IP address should be from same address space (on
same network segment) as the device.
Primary/Secondary DNS IP:
The Domain Name System (DNS) is an internet "phone book" which translates domain
names to IP addresses. These fields identify the server IP addresses of where the device
looks for the translation source.
Primary DNS server IP address
should be specified for the device management purposes.
Secondary DNS
server IP address is optional. It is used as the fail-over in case the
primary DNS server will become unresponsive.
Spanning Tree Protocol:
Multiple interconnected bridges create larger networks using the IEEE 802.1d Spanning
Tree Protocol (STP), which is used for finding the shortest path within network and to
eliminate loops from the topology.
If the STP is turned on, the Bridge device will communicate with other network devices by
sending and receiving Bridge Protocol Data Units (BPDU). STP should be turned off
(selected by default) when the device is the only bridge on the LAN or when there are no
loops in the topology as there is no sense for the bridge to participate in the Spanning Tree
Protocol in this case.
Bridge mode Firewall Configuration Settings
Firewall
functionality on bridge interface can be enabled using the "Enable Firewall"
option. Bridge Firewall rules can be configured, enabled or disabled while using Firewall
configuration window which is opened with the "Configure" button.
Firewall entries can be specified by using the following criteria: Interface the interface
(WLAN or LAN) where filtering of the incoming/passing-through packets is processed; IP
Type sets which particular L3 protocol type (ICMP, TCP, and UDP) should be filtered;
Source IP/mask is the source IP of the packet (specified within the packet header), usually
