The Network Services > DHCP > DHCPv6 Relay tab allows you to configure a DHCPDynamic Host Configuration Protocol relay for IPv6. The DHCP service is provided by a separate DHCPv6 interface and Sophos UTM works as a relay. The DHCPv6 relay can be used to forward DHCP requests and responses across network segments.
Note – You have to activate IPv6 on the Interfaces & Routing > IPv6 > Global tab to use DHCPv6 relay.
To configure a DHCPv6 relay, proceed as follows:
On the DHCPv6 Relay tab, enable DHCPv6 Relay.
Click the toggle switch.
The toggle switch turns amber and the DHCPv6 Relay Configuration area becomes editable.
Add the interfaces facing clients involved.
Add the interfaces to the clients' network(s) between which DHCPv6 requests and responses should be forwarded.
Add the interfaces facing servers involved.
Add the interfaces facing the DHCPv6 server.
Your settings will be saved.
The toggle switch turns green.
To cancel the configuration, click the amber colored toggle switch.
