Network interface

Top  Previous  Next

Each network interface in GibADMIN is represented as a card on which the various settings like name, static or dynamic IP and starting or stopping the interface can be performed.

 

State: Shows the current state of the network interface: (started) or (stopped).
Start interface start: Click this button to start the interface if the current state is (stopped).
Stop interface stop: Click this button to stop the interface if the current state is (started).
MAC address: Shows the worldwide unique MAC address of the network interface card.

 

TIP: To identify the network interfaces for configuring with GibADMIN, you should write the MAC address on each network interface card. This will help you to connect to the correct network interface card.

 

Interface: Enter a descriptive name for the network card to simplify the configuration of Gibraltar. You can for example enter the names ("ext0", "ext1" ...) for your external IP addresses and ("int0", "int1" ...) for your internal IP addresses. The name must not be "lo" nor start with "eth", "ppp", "slip", "ipsec", "sit" and "wlan". Changing the name for the network interface card later might cause problems with the firewall rules.
Start automatically: Mark this checkbox if you want the network interface to start automatically when Gibraltar boots.
IP address: The option fields dynamic and static fix the allocation for IP addresses for this network interface. If you choose dynamic, the network interface searches for a DHCP server while booting, which transmits the IP address and further network settings. If you choose static you have to enter one (or more) IP address(es) by clicking the button Add IP. This IP address(es) has (have) to be up to the CIDR-Notation (e.g: 192.168.0.10/24 for the IP address 192.168.0.10 with subnet mask 255.255.255.0) to set beside the IP address also the number of bits (subnet mask) used for the identification of the network. You can delete the entries in the element group by activating the checkbox and clicking the button Delete marked entries delete in the heading line afterwards. If you want to delete only one entry, click the button Delete IP address delete besides the entry.
Speed and Duplex mode: Select the speed of your network connection here. If your Internet-Provider requires special network settings for communication with your modem, you have to change this here.

       

ATTENTION: When you change the settings of the network interface card, with which you are configuring GibADMIN, the connection can be interrupted!        

 

ATTENTION: If you change the settings of the network interface card, that builds the connection to the default gateway, you also have to check or maybe reconfigure the settings on the card Routing.

 

Save: Confirm your changes with clicking the button Save.

Bridges

 

If a network interface is part of a bridge, it's no reasonable to set the IP address. That's why network interfaces that are assigned to a bridge, aren't reachable. They are marked by the note (bridged) in the head of the tab.

 

Once a bridge is set, an additional tab for the configuration of the bridge will be created. On this new tab the IP address of the bridge can be configured. Also deleting the bridge happens on this tab.
