Can you share with your experience ?

    Assisted Solution

    I use a secondary lan interface in a different vlan and route traffic accordingly. The Sonicwall will not allow creation of a second ip in the same subnet as your LAN though.

    Accepted Solution

    Sorry, disagree with djcanter. There are three ways to do this:
    1) VLAN'ing as djcanter pointed out (best way)

    2) Use a second physical port on the NSA 240, use the same zone name 'LAN', and route accordingly.

    3) ARP the other subnet to the LAN port (usually X0) and setup a route. Works fine, and here is a tech doc (kind old, but still works) on how to do this;

    to edit my above comment: i use a secondary subinterface on X0 in a different vlan.
