5.6 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:
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. To
make some of these services available, navigate to Network > Configuration > Modify and edit the
Firewall section of the page.
