I have a SonicWALL NSA 2400. WAN X1 is connected to the upstream provider, LAN X0 has two VLANs. The VLANs are 2 and 3. Devices on both VLANs can access the Internet.
However, devices on VLAN 2 can access devices on VLAN 3, and vice-versa. I want to segregate the traffic so that devices on each VLAN can get to the Internet, but not pass traffic back and forth intra-VLAN. How can this be achieved?
