Relay
The Network Services > DHCP > Relay tab allows you to configure a DHCP relay. The DHCP service is provided by a separate DHCP server and Sophos UTM works as a relay. The DHCP relay can be used to forward DHCP requests and responses across network segments. You need to specify the DHCP server and a list of interfaces between which DHCP traffic shall be forwarded.
To configure a DHCP relay, proceed as follows:
-
On the Relay tab, enable DHCP Relay.
Click the toggle switch.
The toggle switch turns amber and the DHCP Relay Configuration area becomes editable.
- Select the DHCP server.
-
Add the interfaces involved.
Add the interface to the DHCP server as well as all interfaces to the clients' network(s) between which DHCP requests and responses should be forwarded.
-
Click Apply.
Your settings will be saved.
The toggle switch turns green.
To cancel the configuration, click the amber colored toggle switch.
