with the router if your host has DHCP enabled.
End IP The End IP Address is where the DHCP server stops
issuing IP addresses. The ending address cannot exceed
a subnet limit of 254; hence the max value for the
default gateway is 192.168.1.254. If the DHCP server
runs out of DHCP addresses, users do not get access to
network resources. If this happens, you can increase the
Ending IP address (to the limit of 254) or reduce the
lease time.
Note:
Note:Note:
Note: If you change the start or end values, make sure
the values are still within the same subnet as the IP
address of the router. In other words, if the IP address of
the router is 192.168.1.1 (default) and you change the
DHCP start/end IP addresses to be
192.168.1.2/192.168.1.100, you cannot communicate
with the router if your host has DHCP enabled.
Lease Time The Lease Time is the amount of time that a network
user is allowed to maintain a network connection to the
router using the current dynamic IP address. At the end
of the Lease Time, the lease is either renewed or the
DHCP server issues a new IP. The amount of time is in
units of seconds. The default value is 3600 seconds (1
hour). The maximum value is 999999 seconds
(About 278 hours).
Enable DHCP Relay
In addition to the DHCP server feature, the router
supports the DHCP relay function. When the router is
configured as DHCP server, it assigns the IP addresses to
the LAN clients. When the gateway is configured as
DHCP relay, it is responsible for forwarding the requests
and responses negotiated between the DHCP clients and
the server.
Relay IP The IP address of the DHCP relay server.
Server and Relay Off
When the DHCP server and relay functions are turned
off, the network administrator must carefully configure
the IP address, Subnet Mask, and DNS settings of every
host on your network. Do not assign the same IP address
to more than one host. Also, your router must reside on
the same subnet as all the other hosts.
