The following Figure 1-4 shows some example IP addresses assigned:
• A managed public IP address is assigned the OnBoard’s eth0 Ethernet
port: 203.1.2.3
The OnBoard requires only one managed public IP address assigned to its
primary Ethernet port. The OnBoard’s secondary Ethernet port (
eth1
)
can optionally be used as described under “Understanding Ethernet Ports
on the OnBoard” on page 41.
• A private subnet IP address is assigned to each service processor’s
dedicated Ethernet port (192.168.49.60 and 192.168.49.61) from a
private
subnet network IP range of 192.168.49.0/24.
Note: The IP addresses assigned to the servers’ primary Ethernet ports on the
production network are not covered in this document; server’s IP addresses
can be whatever suits the needs of the servers’ network administrators.
• A private IP address is assigned to the OnBoard from the same range as
the devices’ IP addresses: 192.168.49.254.
While implementing the addressing scheme, the administrator assigns to
the OnBoard itself one or more IP addresses in addition to the OnBoard’s
public IP address. The OnBoard’s private IP address or addresses are used
by the following:
• By devices when talking to the private Ethernet ports of the OnBoard
• By users who make PPTP or IPSec VPN connections to enable native
IP access
