Our Setup:
Sonicwall 3060 enhanced
Two WAN IP ranges from two different ISP’s (ISP A & B)
Port x0 = LAN  192.X.X.X
Port x1 = WAN  64.X.X.X (ISP-A)
Port x2 = I don’t know if this should be WAN or DMZ  67.X.X.X. (ISP-B)

Currently we direct all outbound internet traffic from the LAN over the ISP -A link. We also use ISP-A bandwidth for VPN access from several remote sites.

Our web servers are members of the company Active Directory group. The web servers also use IP addresses that are within or LAN subnet. So traffic going to our web servers enters our LAN subnet. We are using NAT to direct this traffic to ports 80 and 21 of those systems.

Our goal:
I would like to direct traffice to our public www and FTP sites over our ISP-B bandwidth.  

The problem I encounter:
Our SonicWall’s main WAN IP is set for ISP-A. I have gone ahead set port x2 as DMZ and assigned it a WAN IP from ISP-B. The problem I encounter is when I’m stepping through the Public Server Wizard to set our public server settings. At one point I’m prompted to enter the Servers Public IP Address, where I enter the address I assigned to the DMZ at port x2. The wizard completes but when I look at the Access Rules and NAT settings the wizard created they are entered under the WAN category rather then the DMZ category.

Maybe the settings are fine but it seems that if I chose the IP assigned to DMZ (port x2) during the wizard setup then the access rules should appear under DMZ and not under WAN. What I get are custom Access Rules listed under the WAN category.

Is this setup right or am I missing something?
