Two Private Subnets and User Configuration for Example 2
Configuration of the private subnets shown in Figure A-6 is described in the
following bulleted list:
• The primary Ethernet port is configured with IP address 203.1.2.3 and
subnet mask 255.255.255.0.
• A default route is automatically created using a gateway IP 203.1.2.254,
which the administrator assigned when configuring the primary Ethernet
port.
• Private subnets are configured as aliases to priv0 by defining the
OnBoard side IP addresses and netmasks shown in Figure A-6 and listed
here:
• Private subnet “sub1”
• OnBoard side IP address: 192.168.1.1
• Subnet mask: 255.255.255.0
The above values define a range between 197.168.1.0 and 192.168.1.255
= 256 addresses, of which 254 are usable.
• Private subnet “sub2”
• OnBoard side IP address: 192.168.4.1
• Subnet mask: 255.255.252.0
The above values define a range between 197.168.4.0 and 192.168.7.255
= 1054 addresses, of which 1022 are usable. This subnet is defined with
this address range because device “sp3” and “sp4” have previously been
assigned IP addresses within this range, and the addresses cannot be
changed.
The following figure shows the values entered on the Web Manager
Network → Private subnet screen to implement the private subnets in this
example.
