DMZ: DeMilitarized Zone (Advanced)
A DMZ host is effectively not firewalled in the
sense that any computer on the Internet may
attempt to remotely access network services
at the DMZ IP address. Typical uses involve
running a public Web server or sharing files.
Input the IP Address of a single device in
your network to create a DeMilitarized Zone for that device. To ensure that the IP address of the selected device remains consistent,
go to the "Reservations" section under Network Settings → DHCP Server and reserve the IP address for the device.
As with port forwarding, use caution when enabling the DMZ feature as it can threaten the security of your network. Only
use DMZ as a last resort.
Application Gateways
(Advanced)
Enabling an application gateway makes
pinholes through the firewall. This may be
required for some applications to function, or
for an application to improve functionality or
add features.
Exercise caution in enabling application
gateways as they impact the security of
your network.
Enable any of the following types of
application gateways:
• PPTP: For virtual private network
access using Point to Point Tunneling Protocol. This is enabled by default.
• SIP: For Voice over IP using Session Initiation Protocol.
• TFTP: Enables file transfer using Trivial File Transfer Protocol.
