Configuring Private Subnets
Clicking the “Add Subnet” button on the “Configure Subnets” screen brings up the “Private Subnet configuration” dialog shown in the following screen example.
“Configure Subnets” Screen—Wizard: Add Subnet Dialog
At least one private subnet must be defined to enable devices that are connected to the OnBoard’s private Ethernet ports to communicate over the Internet via the OnBoard’s public IP address. Any number of private subnets may be configured.
The following table defines the information that the administrative user must supply in the fields that define a subnet.
Devices use this address when communicating with the OnBoard. The OnBoard uses this address when communicating with devices. This address must be within the private subnet’s IP address range.
The OnBoard derives the range of addresses in the subnet from the OnBoard-side IP address and the subnet mask.The OnBoard uses the specified information to create a route to the subnet in the OnBoard’s routing table.
The example in Network Æ Private Subnets: Add Subnet Dialog shows a private subnet name of “net1,” an OnBoard side IP address of 192.168.0.254, and a subnet netmask of 255.255.255.0. The private subnet address derived from this configuration is 192.168.0.0.
Network Æ Private Subnets: Add Subnet Dialog
Since the broadcast address in the example is 192.168.0.255 (by convention) and the OnBoard’s address is 192.168.0.254, the administrator can assign an IP address out of the remaining available IP addresses between 192.168.0.1 and 192.168.0.253 when configuring a connected device.
Multiple private subnets may be needed if IP addresses are already assigned to connected devices’ Ethernet ports and if the IP addresses are not in the same range.
