Adding A Second DHCP Scope

Mr_Brightside

Hi,

We're running out of internal IP addresses due to the amount of non company items being put onto the Wifi (phones, tablets etc) and so need to add a second DHCP scope to create some more but while still allowing traffic between the two sets of IP addresses so people can access printers and file shares.

The Sonicwall is running SonicOS Enhanced 6.5.4.11-97n

Could somebody give me a step by step guide on how to add this second scope and allow it to talk to our current address scope ?

Mr_Brightside

We do also have some CCTV cameras which are on static addresses outside of the scope which is being assigned by DHCP at the moment so obviously a solution that doesn't break them would be preferable :-)

You can create additional Trusted zone (LAN2) and assign on of the free interface, Follow the below KB.

NB: To allow communication within Zones by creating automatically Access Rules that allow traffic to flow between the interfaces of a Zone instance, select Allow Interface Trust. Otherwise, deselect the Allow Interface Trust check box. This option is enabled by default, but is often disabled when setting up Guest Services.

NB: Once you done above steps; configure the new DHCP pool for the new zone. Follow the below KB:
