DESCRIPTION
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.
Specify the IP addresses up to three DNS servers for the DHCP clients
to use. Use one of the following ways to specify these IP addresses.
Custom Defined - enter a static IP address.
From ISP - select the DNS server that another interface received
from its DHCP server.
NXC - the DHCP clients use the IP address of this interface and the
NXC works as a DNS relay.
Type the IP address of the WINS (Windows Internet Naming Service)
server that you want to send to the DHCP clients. The WINS server
keeps a mapping table of the computer names on your network and
the IP addresses that they are currently using.
Specify how long each computer can use the information (especially
the IP address) before it has to request the information again.
Choices are:
infinite - select this if IP addresses never expire
days, hours, and minutes - select this to enter how long IP
addresses are valid.
Select this option to have the NXC enforce links between specific IP
addresses and specific MAC addresses for this VLAN. This stops
anyone else from manually using a bound IP address on another
device connected to this interface. Use this to make use only the
intended users get to use specific IP addresses.
Select this option to have the NXC generate a log if a device
connected to this VLAN attempts to use an IP address that is bound to
another device's MAC address.
Configure a list of static IP addresses the NXC assigns to computers
connected to the interface. Otherwise, the NXC assigns an IP address
dynamically using the interface's IP Pool Start Address and Pool
Size.
