sonicwall-multiple IP's for same interface

Question

I am new to sonicwall.Is there any way to add multiple ip's to a sonicwall interface ?. In my lab there are two local networks connected to same switch (networks are overlapped). I need to communicate these network through the same sonicwall interface( other interfaces are used for other different networks) A sample diagram of my network follows.

Solution 1

You can create a sub-interface on your LAN interface (X0, usually) and use VLAN tagging to separate the traffic. In Network > Interfaces there is a "Add Interface" button.

Solution 2

Yes, you can do this, it's not intuitive though. Also, you should have been able to find the documentation through Google?

Here's the document: http://www.sonicwall.com/downloads/supporting_multiple_firewalled_subnets_on_sonicos_enhanced.pdf

Example #1 Default NAT Mode with secondary subnet

1. Create Static ARP entry for the gateway address of secondary subnet on the LAN interface
2. Create address object for secondary subnet
3. Add static route for the secondary subnet

What does the documentation say?

i need to use this secondary subnet for vpn tunnel. Is that possible ?

Try it and see? Sounds like a rather silly setup anyway. Plus I've already done too much of your work for you.

I tried that.But it need a manageable switch too ?

Yes, you need to be able to do VLANs on your switch. Doing this set up, we had 4 different networks all configured on X0 for a particular project.
