In the DHCP Advanced Settings dialog, you can enable the Trusted Relay Agent List option using the Default Trusted Relay Agent List Address Group or create another Address Group using existing Address Objects.
When a server is assigned as the internal DHCP server for DHCP over VPN Central Gateway, DHCP messages that come from the VPN tunnel are always bypassed.
To enable the Trusted Relay Agent List option and select the desired Address Group
Select the Address Group from Default Trusted Relay Agent List. This option includes all existing address groups as well as the Create New Address Object Group option.
To create a custom Address Group for this option, select Create New Address Object Group. The Add Address Object Group dialog displays. For information on how to configure Address Groups, see the SonicOS Object Administration Guide.
Click OK to enable the Trusted Relay Agent List option with the selected Address Group.
