We have a SonicWALL 2400. Is there any way to assign multiple interfaces to the same LAN subnet?
Basically, we would like to have X1 for the WAN and X0, X2, X3 and X4 connected to 4 devices that would form a LAN.
Due to limited space, we are unable to add a switch to do this.
Yes, The SonicWALL does this by default.
Go through the Setup Wizard and you can select the radio-button for the setup where X1 is WAN and all other ports are set to the LAN Zone. You can also do two WAN interfaces and the rest to the LAN. These are the options available in the Setup Wizard, but if you want to change more granuarly you can simply go to each interface and assign it to the appropriate Zone.
Set your other three ports to LAN zone and the SonicWALL will switch all ports in that zone.
This is not possible using the Firewall model specified in the question.
The final solution was to get more space to add a switch behind the firewall.
When assigning the Port, set the zone to LAN or whichever subnet you want to share with and then for mode, choose "PortShield Switch Mode". It will then give you the option of a port (X0 for instance) to link to. Now your new port is a switch port connected to the X0 LAN.
