8.1.4 Manual IP Configuration of Client Devices

The client devices connected via the Ethernet interface that use static IP addresses must have

addresses that are within the subnet of the Ethernet interface.

If the local DHCP server is enabled for the Ethernet interface, IP addresses must be reserved

for statically-configured devices by setting the DHCP reserve parameter. This will reserve the

specified number of IP addresses at the bottom of the IP range for the interface. For example,

if the interface has been assigned the IP address 10.2.4.225, the netmask 255.255.255.224,

and the DHCP reserve value 5, the IP addresses 10.2.4.226 through 10.2.4.230 will be

available for use by statically configured devices. The remaining IP addresses in the

interfaces address space can be assigned by the DHCP server to other client devices.

CLI

The number of IP addresses reserved for statically-configured devices connected to the

Ethernet interface is set with the „dhcp.reserve‟ parameter in the „eth0‟ interface.

Web GUI

The DHCP reserve value can be set via the web interface using the “DHCP” sub-tab on the

“DHCP” tab on the “System Parameters” page (see Figure 30).

8.2 IP Configuration for Gateway Nodes

When an EnRoute500 is configured as a gateway, the Ethernet interface is used to provide

backhaul capability by connecting it to a WAN or directly to the Internet. Clients cannot connect

to the EnRoute500 through the Ethernet interface when operating in this mode. The Ethernet

interface IP address can either be acquired from a DHCP server on the WAN or be set

manually.
