Valid lifetime
Using the lease time, you can define how long an allocated address is to be reserved
for a device. Select a low value if it frequently occurs that devices are linked with the
LAN for a short time.

Static IPv6 addresses
Statically assigned IPv6 addresses
In this screen you can direct the DHCP server to always assign a specific IPv6 address
to a certain device. The device will be identified by the hardware address of its network
adapter (MAC address). To add a static address mapping, please type the desired IP
address, a name and the MAC address of the device into the respective fields. The
name is intended for your reference, so you can specify an arbitrary value. The MAC
address is to be stated in hexadecimal form with the single bytes separated by colons
(e.g. 0a:43:94:fc:83:0e).
If the network adapter of one of the devices listed here is
replaced, the MAC address of the device will change. Adjust the
corresponding entry accordingly.
If the device is actually a router you can even assign an IPv6 prefix for distribution
further downstream. SX-GATE will automatically configure the required route for the
prefix.
The prefix must not overlap with other local networks. In
particular the IPv6 address assigned to the router must not be
part of the assigned prefix.
Both, the assigned IPv6 address and the prefix may be based on a dynamic prefix
SX-GATE requested from your provider. Therefor you can also select from the list of
IPv6 addresses and prefixes defined in menu "Definitions > IP objects" when adding a
new entry. Please add entries of type "IPv6 address" or "IPv6 prefix" as appropriate to
subdivide the prefix SX-GATE received from the provider.

DHCPv6 network parameters
Most of the setting of this screen refer to SX-GATE. That's why the corresponding
values are used by default. However you can alter these settings if required.
