A dmz would be better if you have multiple public IPs. If you just have one public IP use port forwarding and leave the server on your LAN.

Question
DMZ or LAN server
I have a crm server that i will be installing, it is not hosting an sql database. i've been told i can leave it on the LAN and just open port 443. do i want to really do that or can i put it on the dmz and do the same with a little fine tuning on access rules?
i was told the dmz would expose more than what the LAN side would expose?
Thoughts?

let me be more detailed in my scenario:
Pro2040 LAN: 192.168.6.1
SQL on LAN: 192.168.6.10
Pro2040 WAN: 24.5.6.2
DMZ : 24.5.6.3
NAT DMZ www server: 192.168.17.3
access rule #1: wan src: 24.5.6.3 lan dstn: 192.168.6.10 port 1433
access rule #2: wan src: * lan dstn: 192.168.17.3 port 443
in this scenario the www server is on the dmz, if compromised the lan is safe.
external users land on dmz server, transactions take place using access rule #1.
would this configuration work and is it better than having a device on the lan and opening port 443?
i think it's my misunderstanding how dmz works, are devices on the dmz still behind the firewall?

Personally I would never use the DMZ, like you stated, you open up way too much . Opening the specific ports that you need is much safer then exposing the entire machine. I would set a static IP to the machine, open only the ports that must be open, and forward them to the static IP you set for that machine, forward port 80 to 80 on that IP.(keeps them out of the router, and directs them to the server) That would be the basics of the basics to get you going.
