DHCPv6
UTMuser@firewall.name.fqdnNetwork 
Configured DHCPv6 pool
The DHCPv6 address pool setup is only slightly different from the DHCP setup with IPv4.
Basic knowledge of IPv6 can be found here.
Define IPv6 address on interface
UTMuser@firewall.name.fqdnNetworkNetwork configuration 
Schnittstelle IP-Adresse hinzufügen
First, an IPv6 address with subnet and the corresponding zones must be entered on the interface on which IPv6 is to be "spoken". This IP determines the range in which the DHCP pool is located:
Configuration at menu / edit Interfaces / Tab IP Addresses
An IP address can be entered directly in the click box, in this example »2001:DB8::1/64.
Setting up the DHCP Pool
In Schritt 1 muss eine eindeutiger Name für den Pool, sowie die Start- und Endardresse angegeben werden.
Der Name ist frei wählbar, Pool-Start- und Endadresse sind Adressen aus dem vorher definierten Subnetz.
Finish the setup with the button

Nachdem der Pool korrekt angelegt wurde, kann dieser mit bearbeitet werden.

DHCP Setup
The button opens a dialogue for the DHCP settings.

| Ignore other SDHCP-Servers (IPv4): | No | If Yes is enabled, other DHCP servers for IPv6 are ignored. | |
Static DHCP
If hosts are to be assigned predefined IP addresses ( fixed IPs bound to the MAC address, but assigned by the UTM), these IPs can be reserved with static leases:
Configuration under Tab Static DHCP Button
| Host: | Hostname | Meaningful host name | UTMuser@firewall.name.fqdnNetworkNetwork configuration  Dialogue Add lease
|
| Ethernet: | 00:00:00:00:00:00 | MAC address of the host | |
| IP: | IP address to be reserved exclusively for this host | ||
| Saves and takes over the lease | |||
|
notempty Important: Leases must necessarily be in an existing DHCP pool!

notempty Joint use of static and dynamic IP addresses within a pool is possible. | |||
Static leases outside a pool
| Existing static leases that are not within a DHCP pool must be changed! If such leases are detected after an update, a message is displayed prompting to adjust the DHCP settings.

Widget
In the administrator interface of the UTM, there is a DHCP widget that provides an overview of the existing DHCP connections.
