eth0.ip.netmask = 255.255.255.224 [read-only]

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

statically-configured devices by setting the ‘dhcp.reserve’ parameter in the ‘eth0’ interface.

This will reserve the specified number of addresses at the bottom of the IP range for the

interface. For example, if the interface has been assigned the address 10.2.4.225, the netmask

255.255.255.224, and the ‘dhcp.reserve’ value 5, the addresses 10.2.4.226 through 10.2.4.230

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

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

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 address can either be acquired from a DHCP server on the WAN or be set manually.

8.2.1 DHCP

When configured as a gateway, the EnRoute500 can be set to obtain an obtain an address for

its Ethernet interface using DHCP. To enable the DHCP client mode on the Ethernet interface,
