Configuring DHCP on the optional network
Just as with the trusted network, you can use the Firebox as either a
DHCP server or DHCP relay. To configure the Firebox as a DHCP
server:
1 If you have not already done so, use your browser to open the
Firebox X Edge configuration pages. Select Network =>
Optional.
The Optional Network Configuration page appears.
2 Select the Enable DHCP Server on the Optional Network
checkbox.
3 Type the first IP address and last IP address that is available for
the computers that connect to the trusted network in the
applicable fields.
The address range must be on the same network as the optional IP
address. For example, if your trusted IP address is 192.168.200.1, the
range should be from 192.168.200.2 to 192.168.200.252.
