Click Network Settings to configure the hostname, DNS, domain name, IPv4 default gateway and
IPv6 default gateway.
Network modes
The appliance provides agentless remote access and control. No special software or drivers are
required on the attached servers or client.
The appliance has three physical network interfaces (eth0, eth1, priv0). Each interface has an
individual MAC address and can be configured for normal or failover modes. Only the public GB1
(eth0) and GB2 (eth1) are visible to the user interface. The 40 private target ports are virtually
configured to connect through the internal priv0 interface.
To configure individual ports, see Port configuration on page 50.
NOTE: Changes to the appliance network mode will invalidate default firewall rules and can interrupt
communication with the appliance. See below for more information.
Placing the appliance into Failover mode or adding eth0 or eth1 to a Bridge group will disable the IP
addresses currently assigned to some/all appliance interfaces. New interfaces will be activated
(Failover = bond0, Bridge group = <group name>). By default, the new interface will not inherit any
former IPs assigned to either eth0 or eth1. For best results when placing an appliance in Failover
mode or creating a Bridge group, the operator should perform the configuration changes via the
VGA console or the serial Setup port to avoid losing communication access to the appliance. All
firewall rules that reference interfaces replaced during the network configuration change should be
edited to ensure proper network communication when operating the appliance in the new mode.
(i.e. eth0/eth1 must be replaced with bond0 where applicable).
NOTE: The default IP addresses for the appliance are: GB1 (eth0) = DHCP, GB2 (eth1) = 192.168.1.10
Normal
In Normal mode, the public interfaces and the public target ports are separated by a firewall. GB1
and GB2 function independent of each other and can assume individual IP addresses. Only a
single gateway can be defined for the appliance, but static routes are helpful for enabling the
appliance to communicate with various subnets from either interface.
For example: An appliance with GB1 connected to a 192.168.200.x/24 network with a gateway of
192.168.200.1. GB2 is connected to a 10.1.0.x/24 network with a gateway of 10.1.0.1. If the default
gateway for the appliance is set to GB1 (eth0), then the appliance will not be able to communicate
