However, for applications that require unrestricted access to the Internet, users can configure a specific client/server as a demilitarized zone (DMZ). For this special DMZ host, it will be exempted from the limitation of the firewall, but also the protection from the firewall. A checkbox is provided to enable/disable the whole firewall function.    Enable Firewall Module    Enable SIP Application Layer Gateway Service
