Configuring The Lan; Enable/Disable Dhcp - Asus AAM6020BI-T4 User Manual

4.5

Configuring the LAN

By default, your CPE has DHCP server (LAN side) enabled. If you already have a DHCP server running on
your network, you must disable one of the two DHCP servers; if you plug a second DHCP server into the
network, you will experience network errors and the network will not function normally.
4.5.1

Enable/Disable DHCP

To enable or disable DHCP go to the Home screen, Click setup. Under LAN Setup, select DHCP
Configuration. This will bring up the screen shown in Figure 9.
The Start IP Address is where the DHCP server starts issuing IP addresses and the End IP Address is where
the DHCP server stops issuing IP addresses.
The Lease Time is the amount of time a network user will be allowed connection to the Router with their
current dynamic IP address. The amount of time is in units of minutes; the default value is 3600 sec (60
minutes).
Note: If you change the start or end values, make sure the values are still within the same subnet as the
CPEs IP address.
In addition to the DHCP server feature, the CPE supports the DHCP relay function. When the CPE is
configured as DHCP server, it assigns the IP addresses to the LAN clients. When the CPE is configured as
DHCP relay, it is responsible for forwarding the requests and responses negotiating between the DHCP
clients and the server. See figure 10.
