an IP address, the Bridge will forward the request to up to two
network DNS servers.
NOTE: Fortress’s
FastPath Mesh
functionality includes
automatic RFC-4193
IPv6 addressing inde-
pendent of network IPv6
DHCP services (see Sec-
tion 3.2.1).
When FastPath Mesh is used for bridging and the FastPath
Mesh network is attached to a conventional hierarchical
network, internal DHCP services obtain default gateway and
DNS server settings from locally configured values. In addition,
the Bridge passes DHCP client IP address-to-name mapping to
the independent FastPath Mesh name resolution function,
permitting all nodes in the FP Mesh network to reach DHCP
clients by name, as well as by IPv4 address. Refer to Section
3.2.1.1 for more on FastPath Mesh bridging.
Both internal DHCP servers are
Disabled by default.
If you enable the Bridge’s internal IPv4 DHCP server, you must
specify the lowest and highest IPv4 addresses in the Bridge’s
IPv4 DHCP address pool.
If you enable the Bridge’s internal IPv6 DHCP server and leave
Auto Addressing at its default of Enabled, you do not need to
manually define the service’s address pool. Alternatively, you
can optionally disable
Auto Addressing, and specify the pool’s
start and end IPv6 addresses.

Although address formats are different, the four basic settings
that configure the Bridge’s IPv4 and IPv6 DHCP services are
the same:
Admin. State - determines whether the Bridge will serve IP
addresses to network devices (
Enabled) or not (Disabled).
Both DHCP services are
Disabled by default.
Max. Lease Time - determines the period of time leases
issued to DHCP clients by the service are valid, in minutes
between
1 and 525,600 (365 days). The default for both
servers is
60 minutes.
IP Range Min. and IP Range Max. - define the start and end
IP addresses within the service’s DHCP address pool:
For the IPv4 DHCP service, you must enter IPv4
addresses in the usual format when you enable the
server.
For the IPv6 DHCP service:
