DHCP End IP
(Subscriber
Module NAT
Mode, Router
Mode)
Configure the highest IP address in the DHCP pool that can be issued to a DHCP client.
Preferred
DHCP DNS
Server
(Subscriber
Module NAT
Mode, Router
Mode)
Configure the primary DNS Server IP address which will be used to configure DHCP
clients (if local DHCP Server is set to Enabled).
Alternate
DHCP DNS
Server
(Subscriber
Module NAT
Mode, Router
Mode)
Configure the secondary DNS Server IP address which will be used to configure DHCP
clients (if local DHCP Server is set to Enabled).
DHCP Lease
Time
(Subscriber
Module NAT
Mode, Router
Mode)
Configure the time for which a DHCP IP address is leased. When the lease time expires,
the DHCP client must renew IP addressing via DHCP request.
Static Routes (Subscriber Module Router Mode)
Static Routes
(Subscriber

Mode)
When Enabled, it allows the operator to create static routes that will apply to both the
Wireless and Ethernet interface of the SM.
This allows operators to configure a custom table of explicit paths between networks.
Static routing is often used as a method to reduce the overhead of processing dynamic
routes through a network when the specific path is known (or, it is simpler to define a
specific path). Static routing is also used as a backup when dynamic routing protocols
fail to complete a route from one network to another.
In router mode, the Static Routes table is referenced by the SM to forward/filter
packets to a particular destination configured by the user based on the IP addressing
information contained in the table.
Since static routes do not change with network changes, it is recommended to only use
static routes for simple network paths that are not prone to frequent changes
(requiring updates to the routes configured on the ePMP SM).
It is important to consider each hop in a static route’s path to ensure that the routing
