Network Settings
Configure external interfaces
You must configure your external network manually if you do not use the Network Setup Wizard.
When you configure the external network, set the method your Internet service provider (ISP) uses to give you
an IP address for your Firebox. If you do not know the method, get the information from your ISP or corporate
network administrator. For information about IP addressing methods, see Static and dynamic IP addresses
.
You can also configure your primary external interface as a wireless interface
.
If your ISP uses DHCP
In the default configuration, the Firebox X Edge e-Series gets its external address information through DHCP.
If your ISP uses DHCP, your Edge gets a new external IP address when it starts and connects to the ISP network.
For more information about DHCP, see About DHCP relay agents
.
To manually set your Firebox to use DHCP on the external interface:
1. To connect to the System Status page, type
https:// in the browser address bar, followed by the IP
address of the Firebox X Edge trusted interface.
The default URL is: https://192.168.111.1
2. From the navigation bar, select Network > External.
The External Network Configuration page appears
3. From the Configuration Mode drop-down list, select DHCP Client.
4. If your ISP makes you identify your computer to give you an IP address, type this name in the Optional
DHCP Identifier field.
5. Click Release if you want to give up the current DHCP-assigned IP address for the Edge. Click Renew
to request a new DHCP-assigned IP address for the Edge from your DHCP server.
6. Click Submit.
