Hot LAN
Hot LAN (or “Hotspot Mode”) allows you to create a separate LAN network for
untrusted systems. Typically, a Hot LAN is used for:

Servers open to the Internet (web server, mail server)

Guest networks

Wireless networks
A Hot LAN is able to access the Internet, but is not able to access any systems on
a LAN. As an example, a Hot LAN can be configured in an office meeting room
used by non-employees. Users in the meeting room could access the Internet and
each other, but not the LAN used by company employees.
DMZ In NSG, a DMZ interface is for managing a block of public Internet IP addresses.
If you do not have a block of public IP addresses, then use the Hot LAN role of
your IP Settings. A typical DMZ setup looks like:

WAN: An IP addresses for connecting to the Internet

LAN: A private network on 192.168.x.x

DMZ: A block of Internet IPs (e.g from 216.138.245.17 to
216.138.245.31)
NSG GUI has a DMZ firewall configuration page to manage firewall policies on
the DMZ network.
