DESCRIPTION
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 this interface enforce links between specific
IP addresses and specific MAC addresses. 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 interface 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.
Click this to create a new entry.
Select an entry and click this to be able to modify it.
Select an entry and click this to delete it.
This field is a sequential value, and it is not associated with a specific
entry.
Enter the IP address to assign to a device with this entry's MAC
address.
Enter the MAC address to which to assign this entry's IP address.
Enter a description to help identify this static DHCP entry. You can use
alphanumeric and ()+/:=?!*#@$_%- characters, and it can be up to
60 characters long.
Have the interface use either the factory assigned default MAC
address, a manually specified MAC address, or clone the MAC address
of another device or computer.
