Set the DMZ up as a SEPARTE private range, and NAT taht on to a differen't ip addres or set of addresses in the publich range available. e.g. <br />
<br />
LAN = 192.168.168.1/24<br />
WAN = 111.111.111.229/28<br />
DMZ = 172.30.0.1/24<br />
<br />
LAN email server (say) at 192.168.168.33 &nbsp;- NAT 1:1 mapping to 111.111.111.231<br />
DMZ web server (say) at 172.30.0.24 &nbsp;- NAT 1:1 mapping to 111.111.111.232<br />

so move it completely from an externla dmz to an internal network with natting... &nbsp;ok.. &nbsp; just asking because the setup of the 2400 is quite a bit different that the 2040pro(standardOS) that it is replacing.

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
