Enable DHCP server on the trusted network
The DHCP Server option allows the Firebox X Edge e-Series to give IP addresses to the computers on the
trusted network. When the Edge receives a DHCP request from a computer on the trusted network, it gives the
computer an IP address. By default, the DHCP Server option for the trusted interface is enabled.
To use DHCP on the trusted network:
1. Use your browser to connect to the System Status page. From the navigation bar, select Network >
Trusted.
The Trusted Network Configuration page appears.
2. Select the Enable DHCP Server on the Trusted Network check box.
3. Type the first and last available IP addresses for the trusted network. Do not include the IP address of
the Firebox X Edge.
The IP addresses must be on the same network as the trusted IP address. For example, if your trusted
IP address is 192.168.200.1, the IP addresses can be from 192.168.200.2 to 192.168.200.254.
4. Use the Days/Hours/Minutes value control boxes to set the length of time for each DHCP lease the
Edge gives.
5. If you have a WINS or DNS server, type the WINS Server Address, DNS Server Primary Address, DNS
Server Secondary Address, and DNS Domain Suffix in the correct text boxes. If you do not enter a
value, the Firebox X Edge uses the same values as those used for the external network.
6. Click Submit.
