Configuring and managing the IGW3000

After applying these settings with the Apply button, the network configuration will be changed.
Notes
• During DHCP configuration, take special care to ensure that the IP address, Netmask,
Gateway and Range settings match each other. Under normal circumstances, the IP address
and the gateway address should be the same.
• It is recommended to leave Primary DNS and Secondary DNS at their default settings, which
will allow you to use your operator’s DNS servers. However, these addresses can be changed
to use other servers, e.g. Open DNS.
Managing the port forwarding rules
The Port Forwarding submenu provides advanced options that control which services on your
home network should be made available to the whole world. In order to configure services through
this menu, complete the following steps:
1.
Click Network > Port Forwarding to open the Port Forwarding tab.
Figure 16. Port Forwarding tab in the Network menu
2.
To add a port forwarding rule, use the following fields under the solid line:
• Name: used for your reference. It should identify the kind of service provided. For example,
if you want to serve Internet pages using the HTTP protocol, set this to “Web server”.
• Protocol: specifies either TCP, UDP or TCP/UDP protocol. Most Internet services use
TCP, and a few use UDP. To select the correct protocol, consult the manual for the service
you are providing. If you are still unsure about the protocol type, select TCP/UDP.
• Ext. port: specifies the port that should be forwarded from the external (Internet) side. To
find the right port number, consult the manual for the provided service.
• Address: specifies the IP address of the LAN side network equipment that will get the
requests. If an incorrect IPv4 address is entered, the text will appear red.
• Port: specifies the private port on the LAN side. This value should usually remain the same
as the value of Ext. port. In rare cases, where a service should be available on one TCP
or UDP port from the Internet side, but redirected to another port on the server providing
the actual service, these values might be different.
• Loopback: enables or disables NAT loopback for a given port forwarding rule.
• Use port range: allows to specify the forwarding rule for a range of ports (like for FTP
in the screenshot above).

When you are finished editing the port forwarding rule entry, click the Add button to add it
to the list.
