Release a DHCP Lease

STEP 1

STEP 2

From the LSM menu, select Network > DHCP Server.

On the DHCP Server page in the DHCP Client Summary table, click the Release icon to end the lease and update the table.

Configure DHCP Server

You can configure the device to be your DHCP server, thereby allowing computers on your network to obtain an IP address and subnet mask automatically.

Note Ensure that the firewall rules configured on the device allow DHCP clients to send DHCP requests to the correct security zone and to receive their IP address by DHCP. For details, see “Firewall” on page 63.

Default DHCP Configuration

The DHCP server is enabled by default and configured with the default IP Address Group DHCP-Pool which includes 20 IP addresses in the subnet defined for the internal IP interface. These DHCP addresses are 192.168.1.1 - 192.168.1.20. The default lease duration is one hour. You can disable the DHCP server or modify the default configuration based on your network requirements.

You can view and manage the DHCP configuration on the DHCP Configuration page (Network > DHCP Server > Configure DHCP). From this page, you can complete the following tasks:

•Enable/disable DHCP

•Change the lease duration

•Configure the DHCP Address Pool from which the device allocates addresses

•Select DHCP server options for DNS, WINS, and NBX services
