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.
6.4.4
Application Gateways (Advanced)
Enabling an application gateway makes pinholes thru the firewall. This may be required for some applications to function,
or for an application to improve functionality or add features. PPTP and FTP are enabled by default, while SIP, TFTP, and
IRC can be enabled to enhance or enable particular features that use those protocols.
Exercise caution in enabling application gateways as they impact the security of your network.
Click on any of the following to toggle between enabling and disabling the application gateway for each protocol.
• 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.
• FTP: To allow normal mode when using File Transfer Protocol. This is not needed for passive mode. This is
enabled by default.
• IRC: For Direct Client to Client (DCC) transfer when using Internet Relay Chat. You may wish to forward TCP port
113 for incoming identd (RFC 1413) requests (i.e. add a Port Forwarding Rule with 113 set as the "Local Port").
