Network Settings
Enable DHCP server on the optional network
The DHCP Server option sets the Firebox X Edge to give IP addresses to the computers on the optional
network. When the Edge receives a DHCP request from a computer on the optional network, it gives the
computer an IP address. By default, the Edge has the DHCP Server option for the optional interface turned off.
To use DHCP on the optional network:
1. Use your browser to connect to the System Status page. From the navigation bar, select Network >
Optional.
The Optional Network Configuration page appears.
2. Select the Enable DHCP Server on Optional Network check box.
3. Type the first available IP address for the optional network. Type the last available IP address.
The IP addresses must be on the same network as the optional IP address. For example, if your optional
IP address is 192.168.112.1, the IP addresses can be from 192.168.112.2 to 192.168.112.254.
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 related fields. 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.
