Network Definitions

At network definitions is possible to configure the following network interfaces parameters:

• Interface: Interface name;
• Type: Private (for eth0) or public for the others;
• Mode: For the public interfaces it's possible to configure the interface as dynamic, so it will act as a DHCP client;
• IP: Interface IP address with the correspondent network bit mask;
• Network: Network address;
• Broadcast: Network broadcast IP;
• MAC Address: Physical address of NIC.

The Modify will change these parameters. The Insert will add a new IP alias for the interface. Example: eth0:1, eth0:2.

If IPBrick works as an Intranet server (IPBrick.I), it is only necessary to configure the private interface. In this case, public interface (if the server where IPBrick is installed has got 2 network cards) may get with all the default configurations and it shall not have a network cable connected. If IPBrick works like a Communications server (IPBrick.C) or if it accumulates the Intranet and Communications functions (IPBrick.I + IPBrick.C), it is necessary to configure the two network interfaces (in these two situations, the server where IPBrick was installed, shall have two network cards).

To change the network interfaces definitions, it is necessary to click ETH0 and ETH1.

NOTE: The private interface is the first network card detected by IPBrick in the server where it was installed. If the server has a second network plate, this shall be configured as a public interface. The firewall is already configured by default with specific rules to recognize the ETH0 as a private interface and ETH1 as a public interface. If the server has more network cards (ETH2, ETH3...), they shall be considered as private;

NOTE: The ethernet cards MAC address should be associated to all the interfaces, so when the server reboots the interfaces will be always associated to the same NIC.
