Setting DHCP Address Reservations
You can bind a static IP address to a specific hardware device by way
of its MAC address.
1 If you have not already done so, use your browser to open the
Firebox X Edge configuration pages. Select Network => Trusted.
The Trusted Network Configuration page appears.
2 Click the DHCP Reservations button.
The DHCP Address Reservations page appears.
3 Choose a static IP address from the DHCP address pool listed on
the page and type it in the IP Address field.
4 Find the MAC address of the hardware device you would like to
assign the IP address to and type it in the MAC address field.
Click Add. Click Submit.
Configuring the Firebox as a DHCP relay agent
Another way to distribute network addresses to the computers pro-
tected by the Firebox X Edge is to use a DHCP server on another
network. The Firebox can relay DHCP requests to that server and
then send the results back to the computers on the trusted network.
This option is commonly used by network administrators managing
multiple remote offices and allows even remote computers to use
the same network address range.
