6.3.1.3 DHCP
The Network > DHCP screen allows you to configure the GridRouter’s Dynamic Host Configuration
Protocol (DHCP) server function. The GridRouter can be used as a DHCP server which automatically
assigns an IP address to each device on your network.

LAN DHCP
The DHCP settings for devices connected to the GridRouter through the Ethernet connector.
DHCP:
DHCP is enabled by factory default. If a DHCP server is not desired, then select “
Off
“.
Start:
Specifies the 4
th
octet of the IP address to start issuing IP addresses. For example, the default IP
address is “
192.168.0.254
“, so this start value must be less than 253 (192.168.0.253). The default Start
value is “
1
“ (192.168.0.1).
Limit:
Specifies the maximum number of devices that the DHCP server will assign IP addresses to.
Lease Time:
Specifies the number minutes a network user will be allowed connection to the GridRouter
with their current dynamic IP address.
Static IP Addresses
The DHCP server uses the matching IP address instead of allocating a new one from the pool for any
MAC address listed in this file.
Name:
Specifies the name of the rule or end device.
MAC Address:
Specifies the MAC address of the device that will be receiving the static IP address.
IP Address:
Specifies the IP Address to assign to device with the specified MAC Address.
Device Type:
Specifies the type of device receiving an IP address. This value should be “
Generic
“
unless connected to an Echelon Ethernet Data Concentrator (DC).
The Echelon DC requires that its local IP address changes when the GridRouter’s WAN address changes
to ensure that the DC will call back into the NES server. The least time should be around 5 minutes to
ensure that the DC will call back within 5 minutes of the WAN address changing. The local IP address
assigned to the DC will cycle through the range of address specified by the Start and End IP Addresses
each time that the WAN address changes. The suggested range is 10 addresses and 2 is the minimum.
Port forwarding firewall rules that have a “
Static IP Rule
” set to something other than “
None
” will
automatically be adjusted to match the DC’s address.
