ONFIGURATION

You can select static address binding or dynamic address binding accordingly, but 
you can only choose one of them for a given DHCP address pool. 

For dynamic address allocation mode, you should specify address range. Static 
address binding can be deemed as a special DHCP address pool with only one 
address. 

Some DHCP clients may require a fixed IP address, i.e., binding the client MAC 
address to an IP address. Then when the DHCP client with this MAC address 
requests for an IP address, DHCP server will find and allocate the bound IP address 
to the client. 

Perform the following in the DHCP Address Pool View. 

By default, no binding is configured and the client MAC address is set as Ethernet. 

Perform the following in the Interface View.

For the dynamic addresses (including permanent ones or those lease limit dynamic 
ones), you should configure them with address pool range. Currently only one 
address segment can be set to an address pool, which is define by the mask.  

Perform the following in the DHCP Address Pool View.
