What DHCP Does
A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a
DHCP Client (PC or device) upon request.
The client request is made when the client device starts up (boots).
The DHCP Server provides the Gateway and DNS addresses to the client, as well as
allocating an IP Address.
The XRT-501 can act as a DHCP server.
Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP
client. This is the default Windows setting for the TCP/IP network protocol. However,
Windows uses the term Obtain an IP Address automatically instead of "DHCP
Client".
You must NOT have two or more DHCP Servers on the same LAN segment. (If
your LAN does not have other Routers, this means there must only be one DHCP
Server on your LAN.)
The default value 255.255.255.0 is standard for small (class
"C") networks. For other networks, use the Subnet Mask for the
LAN segment to which the XRT-501 is attached (the same
value as the PCs on that LAN segment).
If Enabled, the XRT-501 will allocate IP Addresses to PCs
(DHCP clients) on your LAN automatically when they start
up.The default (and recommended) value is Enabled.
If you are already using a DHCP Server, this setting must
be Disabled, and the existing DHCP server must be
re-configured to treat the XRT-501 as the default Gateway.
See thefollowing section for further details.
The Start IP Address and Finish IP Address fields set the
values used by the DHCP server when allocating IP Addresses
to DHCP clients. This range also determines the number of
DHCP clients supported.See the following section for further
details on using DHCP.

The "Cancel" button will discard any data you have
entered and reload the file from the XRT-501.
