SONICWALL TZ210 NAT policies issue on

Hi everyone,

I'm having issues with the NAT policy config on a new Sonicwall TZ210 Firewall.

I swapped a Linksys RV082 with this new unit which I have already pre-configured. The issue I am having is the NAT policy for Exchange server. The router's main WAN static IP is "216.x.x.197" and I need to setup a NAT policy to the secondary WAN IP '216.x.x.196" so that the incoming traffice on Exchange server can start working again. I am able to send emails out, but they are not coming in from the outside world (basically the world doesn't know that "216.x.x.196" is here).

FYI: the previous router had a DMZ setup on the WAN port for the "216.x.x.196" address, so it automatically accepted requests from the secondary IP. I cannot setup DMZ on the WAN port of the Sonicwall TZ210, so I will have to create a NAT policy.

The MX record points to the secondary WAN IP "216.x.x.196", so I am fighting with the new "enhanced" Sonicwall OS to make it happen.

can anyone please help me?
Thank you,

Ok, here's what you need to do.
If you haven't already create an address object (network>address objects) for that IP, it's on the WAN zone.
Then create the firewall rule to allow incoming SMTP traffic to that IP. WAN>LAN allow source is any and dest is the address object you just created.
Then for the NAT policy you create like this:
source: any>original
destination: address object created above > address object of the exchange server internally
service: smtp (email)> original
interface: any>any

This should do it.
