3.4.2 IP Configuration
The Bridge supports Internet Protocol version 4 (IPv4) and
Internet Protocol version 6 (IPv6).
IPv4 is enabled by default. When it is disabled, the Bridge's
management IP address neither accepts or sends IPv4
packets.
IPv6 is always enabled on the Bridge, a state which is not user
configurable.
3.4.2.1 IPv4 Configuration
The settings that configure Internet Protocol version 4 on the
Bridge include:
IPv4 State - adds the Bridge’s IPv4 address—and therefore
the Bridge itself—to the IPv4 network (
Enabled) or removes
the Bridge’s address (and the Bridge) from the network
(
Disabled). IPv4 is Enabled by default.
IPv4 Address - establishes an IPv4 network address for the
Bridge’s management interface. The default IPv4 address
is
192.168.254.254; it is normally changed during installation.
IPv4 Subnet Mask - provides the correct IPv4 subnet mask
for the Bridge’s management interface.
IPv4 Default Gateway - provides the IP address of the
default IPv4 gateway for the Bridge’s subnet.
In order to re-access the Bridge’s management interface after
changing the Bridge’s IPv4 settings, you must enter the
Bridge’s new IP address into a new instance of your browser.
3.4.2.2 IPv6 Configuration
NOTE: Fortress’s
FastPath Mesh
functionality includes
independent IPv6 ad-
dressing, which can
supply additional IPv6
ULAs (Unique Local
Addresses, refer to Sec-
tion 3.2.1).
Internet Protocol version 6 is always enabled on the Bridge.
You can choose to allow all IPv6 settings to be automatically
configured on the Bridge, opt to manually configure the global
address and IPv6 gateway/metric, or use both manually and
automatically configured global addresses.
When
IPv6 Auto Addressing is Enabled (the default) and there is
an IPv6 router on the network configured to provide the global
prefix, the Bridge will automatically configure a compatible IPv6
global address for itself, displayed under
Other Addresses. If
additional IPv6 routers are present, auto-addressing will
configure additional IPv6 global addresses.
If a network IPv6 router is configured to do so, it will additionally
supply its own address as one of the Bridge’s IPv6
Default
Gateways
, with the appropriate metric. If more than one IPv6
router is present on the network and so configured, the
additional routers will also appear on the list of
IPv6 Default
Gateways
, with their metrics.
If you choose to manually configure IPv6 settings, these
include:
