Configuring the Trusted Network
Setting trusted network DHCP address reservations
You can manually give the same IP address to a specified computer on your trusted network each time
that computer makes a request for a DHCP IP address. The Firebox X Edge identifies the computer by
its MAC address.
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
Click the DHCP Reservations button.
The DHCP Address Reservations page appears.
3
Type a static IP address in the IP Address field. The IP address must be on the trusted network
but outside the DHCP Address pool.
For example, if the trusted network starts with 192.168.111.1, and the DHCP address pool is
192.168.111.2-192.168.111.200, you can enter any address from 192.168.111.201 to
192.168.111.254.
4
Type the MAC address of the computer on the trusted network in the MAC Address field. You
must enter the MAC address as 12 hexadecimal digits with no space, dash, or semicolon
characters. Click
Add .

Configuring the trusted network for DHCP relay
One method to get IP addresses for the computers on the trusted network is to use a DHCP server on a
different network. The Firebox X Edge e-Series can send a DHCP request to a DHCP server at a different
location through a VPN tunnel. It gives the reply to the computers on the Edge trusted network. This
option lets computers in more than one office use the same network address range. In this procedure
the Edge is a DHCP Relay Agent. You must set up a VPN between the Edge and the DHCP server for this
feature to operate correctly.
