SONICWALL TZ210 NAT policies issue on

SONICWALL TZ210 NAT policies issue on

(OP)
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,
