TCP/IP"
on page 47). By default, the residential gateway DHCP server is enabled.
If there is another DHCP server running on your network (on another router), you must
disable one of the DHCP servers.
Sets the first IP address assigned by the DHCP server, in
greater than the IP address value of the residential gateway. For example, if the IP address
of the residential gateway is 192.168.15.1 (default), the starting IP address must be
192.168.15.2 (or higher).
Sets the final IP address assigned by the DHCP server, in dotted-decimal format. It cannot
exceed the subnet limit of 254. For example, the default is 192.168.15.254. If the DHCP
server runs out of DHCP addresses, users cannot access network resources. If this happens,
increase the End IP (to the limit of 254) or reduce the Lease Time.
If you change Start IP or End IP, be sure they are in the range specified by the Subnet IP
Address and Netmask. For example, if the residential gateway IP address is 192.168.15.1
(the default) and you set Start IP and End IP to 192.168.0.2 and 192.168.0.100 respectively,
computers with DHCP enabled cannot communicate with the residential gateway.
Sets the time, in seconds, that a network computer remains connected to the residential
gateway using its current assigned IP address. At the end of this time, the DHCP server
renews the lease or assigns the computer a new IP address. The default is 3600 seconds (1
hour). The maximum is 999999 seconds (about 278 hours).
If selected, the residential gateway forwards requests and responses between the computers
on your network (the DHCP clients) and the DHCP server you chose to use for your network.
If you select Enable DHCP Relay, type the IP address of the DHCP server in dotted-decimal
format.
If selected, you 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. Your
residential gateway must be on the same subnet as the other hosts.
