Set trusted network DHCP address reservations
1. 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.
2. Use your browser to connect to the System Status page. From the navigation bar, select Network >
Trusted.
The Trusted Network Configuration page appears.
3. Click the DHCP Reservations button.
The DHCP Address Reservations page appears.
4. Type a static IP address in the IP Address text box. 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.
5. Type the MAC address of the computer on the trusted network in the MAC Address text box. You must
enter the MAC address as 12 hexadecimal digits with no space, dash, or semicolon characters. Click
Add.
6. Click Submit.
