5.4 Network Mode: NAT/Firewall with DMZ
When the network mode is set to NAT/Firewall with DMZ, the logical network capability is as shown in the
diagram below:
Allworx server

NAT Firewall
Turning on the DMZ moves the WAN network services behind the firewall. This means that even the Allworx
WAN services (POP, SMTP, FTP, HTTP, etc.) are not available by hosts on the WAN. Making some of these
services available can be done in the Firewall section of the Network / Configuration / Modify page.
