Using a DHCP relay agent with a SonicWALL
I have an existing network with multiple VLANs that are routed by a Cisco L3 switch (10.6.0.x/24, 10.6.2.x/24 etc). The Cisco handles all routing for the network and its default gateway is the SonicWALL X0 interface which is connected by a point-to-point L3 connection (10.6.50.x/30). If we wanted to use the SonicWALL as the DHCP server instead of the Cisco switch, can we enable the DHCP relay agent on the Cisco and forward DHCP requests to the SonicWALL? The SonicWALL has no interfaces on any of the VLANs and there doesn't seem to be a way to assign a specific DHCP scope to a specific VLAN without the SonicWALL having an interface on the VLAN in question.
Thanks for any guidance you can provide!
