I'm trying to configure a Sonicwall Nsa 2400 Firmware SonicOS Enhanced , with this configuration:

LAN      X0
WAN X1  Gateway

Like you can see, the two address are private.

My ISP  doesnt do any NAT, only redirect the traffic of my public ip address to my

The problem I have is  that I dont get outbound traffic for my WAN. I have traffic to the LAN, inbount traffic trought PAT, but i dont get traffic to the sonicwall.

Is it possible to make a outbound NAT for the sonicwall with this configuration?

    Private IPs are not routed on the Internet. So, if you were able to browse the internet, your ISP would have to be NAT'ing your internal traffic. If you put a laptop to your ISPs router with an IP address and GW of, can you get to the Internet? What your ISP needs to do is give you a public IP that you can give your sonicwall WAN interface, IF they are truly not NAT'ing, then their hardware must be in transparent or bridge mode. If it's not, then it should be. What kind of internet is it, cable, dsl, t-1?
