Dynamic Ranges
I
When a client makes a request for an IP address, the
Internet Firewall's DHCP server leases an address from
the Dynamic Ranges.
Prior to offering an address from the Dynamic Range to a
requesting client, the Internet Firewall first verifies that the
address is not already in use by another machine on the
LAN.
To create a range of dynamic IP addresses to be
assigned to requesting clients, type the starting number
in the Range Start box, the ending address in the Range
End box and then click Update.
Allow BootP clients to use range
I
Click this check box to have Dynamic BootP clients
configured when they boot. Dynamic BootP clients are
BootP clients that do not have an IP address assigned to
their MAC address. They are similar to DHCP clients
with the exception that leases are not supported.
Delete Range
I
To remove a range of addresses from the dynamic pool,
select it from the scrolling list of dynamic ranges, and
click Delete Range.
Static Entries
I
Static addresses are used by machines that support
BootP or those which require a fixed IP address. For
example, machines running Web or FTP servers require
static addresses.
To create a static IP address to be assigned to a
requesting client, type an IP address and the Ethernet
(MAC) address of the client machine in the appropriate
boxes and click Update.
Delete Static
I
To remove a static address, select it from the scrolling
list of static addresses and click Delete Static.
