Select what type of DHCP service the NXC provides to the network.
Choices are:
None - the NXC does not provide any DHCP services. There is already
a DHCP server on the network.
DHCP Relay - the NXC routes DHCP requests to one or more DHCP
servers you specify. The DHCP server(s) may be on another network.
DHCP Server - the NXC assigns IP addresses and provides subnet

Enter the IP address from which the NXC begins allocating IP
addresses. If you want to assign a static IP address to a specific
computer, use the Static DHCP Table.
If this field is blank, the Pool Size must also be blank. In this case,
the NXC can assign every IP address allowed by the interface's IP
address and subnet mask, except for the first address (network
address), last address (broadcast address) and the interface's IP
address.
Enter the number of IP addresses to allocate. This number must be at
least one and is limited by the interface's Subnet Mask. For example,
if the Subnet Mask is 255.255.255.0 and IP Pool Start Address is
10.10.10.10, the NXC can allocate 10.10.10.10 to 10.10.10.254, or
245 IP addresses.
If this field is blank, the IP Pool Start Address must also be blank.
In this case, the NXC can assign every IP address allowed by the
interface's IP address and subnet mask, except for the first address
(network address), last address (broadcast address) and the
interface's IP address.
