with other 10.x.x.x networks via the gateway assigned to GB2. A static route can be added to the
appliance indicating that 10.1.0.1 should be used to communicate with all 10.x.x.x subnets.
Failover
In Failover mode, the GB1 and GB2 interfaces are both activated and each has a unique MAC
address but they share a common bond0 virtual interface. Only a single MAC exists for the shared
bond0 interface and only a single IP can be assigned to bond0. When data needs to be sent from
the appliance, only GB1 will send it using the bond0 MAC/IP. When traffic is sent to the bond0
MAC/IP, only GB1 will receive it, since only GB1 is responding to ARP requests using the bond0
MAC. If GB1 is disconnected, then GB2 assumes control of the bond0 MAC/IP for all data
exchange.
To configure a network device:
1. From the sidebar, click Network Settings.
2. Enter the hostname (the hostname will be used for e-mail notifications as the sender
address).
3. Use the drop-down list to select Normal or Failover for the mode.
4. Enter the primary and secondary DNSaddresses in the appropriate fields.
5. Enter the domain name.
6. Use the drop-down lists to select the IPv4 and IPv6 default gateways.
7. Click the name of the interface to modify it.
a. Under the IPv4 heading, enter the MTU, address, netmask, broadcast and gateway in
the appropriate fields. Use the drop-down list to select either DHCP or static for method.
b. Under the IPv6 heading, enter the address, netmask and gateway in the appropriate
fields. Use the drop-down list to select either DHCP or static for method.
8. Click Apply.
Bridge Group Configuration
An administrator can choose network interfaces to bridge together into a logical bridge group. This
feature simplifies the creation, deletion and maintenance of bridged interfaces. You can bridge
both physical and virtual interfaces, and bridging supports user-created interfaces as well as the
pre-defined ones.
Abridge group can be created for each virtual and physical interface defined on the appliance.
When a bridge group is created, it will be assigned a Layer 3 IPv4/IPv6 address. When interfaces
are added to a bridge group, a prompt will be displayed, indicating that all IPaddresses assigned to
