Using Static Ip Addresses For Optional Computers; Adding Computers To The Optional Network - Watchguard Firebox X15 User Manual

To configure the Firebox as a DHCP Relay Agent for the optional
interface:
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 Relay on Optional Network check box.
3 Type the IP address of the DHCP server in the related field.
4
Click Submit. You must restart the Edge for the new
configuration to activate.
If the Firebox cannot connect to the DHCP server in 30 seconds, it
uses its DHCP server to give IP addresses to computers on the
optional network. You must enable the DHCP server on the
optional network for the DHCP relay function to operate.

Using static IP addresses for optional computers

You can use static IP addresses for some or all of the computers on
your optional network. If you disable the DHCP server and you do
not have a DHCP server on your optional network, you must manu-
ally configure the IP address and subnet mask of each computer.
You can also configure specified devices with a static IP address. For
example, this is necessary for a Web server or network printer. Static
IP addresses must be on the same network as the Edge optional
interface. Computers with static IP addresses on the optional net-
work must use the optional interface IP address of the Edge as the
default gateway or router.
To disable the Firebox DHCP server, clear the Enable DHCP Server
on the Optional Network check box on the Optional Network Con-
figuration page and click Submit.
Computers on the optional network must use the Firebox's
optional interface IP address as the default gateway. If a computer
does not use the Firebox for the default gateway, it usually cannot
get to the external network or the Internet.

Adding computers to the optional network

You can directly connect only one computer to the Firebox X Edge
optional interface because there is only one optional Ethernet port.
