6.1.3 Port triggering

Introduction

Port triggering allows you to define a set of dynamic port forwarding rules that will be activated as soon as a device sends

traffic to the Internet over a specific port(s), the

trigger port(s)

.

The difference compared to the port forwarding function described in

“6.1.2 Port forwarding” on page 47

is that:



Port triggering rules will only be activated if a local device is sending traffic over one of the trigger ports. So there must be

outbound traffic first.



Port triggering rules forward the traffic to any device that has initiated the communication while port forwarding forward

a fixed IP.



Port triggering rules allow you to translate the port numbers. This means that the incoming port can differ from the target

port.

Procedure

6.1.4 Configure a DMZ Host

Introduction

The Gateway allows you to configure one local device as a De-Militarized Zone (DMZ) host. This means that:



None of the Gateway firewall rules will be applied to this device.



All traffic originating from the Internet will be forwarded to this devices unless there is a port forwarding rule defined for

this type of traffic. Port forwarding rules always have higher priority.

Use a reserved IP address for the DMZ host

Make sure that your DMZ host uses a fixed IP address. If you do not do this, the device might get a new IP address after

some time and the port forwarding rule will no longer be applied to the device and another device may suddenly be acting as

DMZ host. For more information, see

6.2 Assigning a reserved IP to a device

Introduction

By default, each device will get an IP address from the Gateway’s DHCP server. When a device leaves, is turned off or the

lease time of the address has expired, the IP address becomes available and can be re-used for other devices.

When you want to run a service on a network device (for example, a web server, network printer, etc.), it is advised to assign

a reserved IP to the device. This way, the device will always be reachable on the same address and there is no risk that you are

accessing the wrong device.

How to assign a reserved IP

Proceed as follows to do so:

1

Browse to the Admin Tool.

“Accessing the Admin Tool” on page 25
