Example: Assigning TCP/IP Settings for Hosts Using DHCP (NSM Procedure)
The Dynamic Host Configuration Protocol (DHCP) automatically assigns TCP/IP settings for the hosts on the network. Different security devices support different DHCP roles:
DHCP clients receive a dynamically assigned IP address.
DHCP servers allocate dynamic IP addresses to clients.
DHCP relay agents receive information from a DHCP server and relay that information to clients.
Some devices can simultaneously act as a DHCP client, server, and relay agent.
To assign TCP/IP settings to hosts using DHCP:
In the NSM navigation tree, select Device Manager > Devices.
Select a security device and then double-click the device on which you want to define forced timeout. The device configuration appears.
In the device navigation tree, select Network > Interface.
Double-click a trust interface. The General Properties screen appears.
Select DHCP in the navigation tree, and for the DHCP Mode, select Server.
Configure the server settings as follows:
For DHCP Server Auto Processing, select Enable DHCP Server.
For DNS #1, #2, and #3, enter 18.104.22.168.
For Domain Name, enter acme.com.
For Client Gateway, enter 22.214.171.124.
For Lease Time (Minutes), the default is 4320 minutes.
For Netmask, the default is 0.
For NetInfo Server #1 and Server #2, enter 126.96.36.199.
For POP3, enter 188.8.131.52.
For SMTP, enter 184.108.40.206.
For WINS#1 and WINS#2, enter 220.127.116.11.
Select Enable Next Server IP.
