Can SSG-140 transfer traffic in case it?

Hello all,

I want to know whether SSG-140 transfer traffic in case below captured picture.

As you can see the picture, SSG-140's IP is 2.2.2.2

Source IP is 1.1.1.1, and Destination IP is 3.3.3.3



From now on, I've done SSG-140 in case that destination IP was same as SSG-140's.

But now I have to configure that everything(Source, Destination and Firewall's IP) is same...

To sum up, my question is ...

1. Even though every IP is not same, can I configure it?



Is it right setting?;; Please check guys.

2. I'm wondering if I configure L2 mode or Route mode...? 

Should I configure vlan?...

Could you advise me how to set up the machine?

Regards,

SK.
