Sonicwall TZ190 Enhanced OS

I have a TZ190 and need to create a DMZ for a Web Server.  The web server needs to be able to communicate with a server inside my network. i the 172.16.60.x network.  This is my fist time creating a DMZ so I'm learning, and of course, only have two days to get this done.  

Right now my network looks like this:

Comcast bridge connects to the TZ190 WAN port which has a Public IP Address.  
The LAN port on the TZ190 has an IP address of

Can I create a DMZ using the OPT port on the TZ190, lets call that subnet 192.168.1.xand stick the WebServer in the DMZ with only one NIC or should I have NIC's in the server?  The server will require a NAT'd address for it's public interface, but just to recap, it also needs to get into my 172.16.60.x network.  

If I need to split this up into multiple questions no problem.

Just curious, why are you putting the web server in a dmz? Why not put the web server on your internal network and just open up port 80 and / or 443?
As bcdudley mentions, it can be located on the LAN side, but putting in the DMZ does give you an extra layer of security on the LAN....

Yes, you can put the web server in the "DMZ" off the OPT port as you mention.... assign the OPT port to the DMZ Zone, the use the 'wizard' to configure the web server as a 'public' server. The wizard should create the correct firewall rules both for access from the WAN and access from the LAN. That NAT policy that is created should route LAN traffic to the DMZ...

Thanks for the responses.  

I am required to stick the server in the DMZ per our company security policy and only open up (as was stated by bcdudley) ports 80 & 443.

Thanks for the confirmation Bwaring.  I'm going to take a stab at this and see how it goes.
