If Your Isp Uses Dhcp - Watchguard Firebox X15 User Manual

It can be the same IP address each time, or it can be a different
IP address.
• Static IP address - Network administrators use static IP
addresses to manually give an IP address to each computer on
their network. A static IP address can be more expensive than a
dynamic IP address because static IP addresses make it easier to
set up servers. Static IP addresses are also known as manual
addresses.
• PPPoE - Many ISPs use PPPoE (Point to Point Protocol over
Ethernet) to give IP addresses to each computer on their
network.
To configure your Firebox® X Edge, you must know how it gets the
IP address for the external interface. If you do not know the
method, get the information from your ISP or corporate network
administrator.

If your ISP uses DHCP

The default configuration sets the Firebox X Edge to get 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" on page 5.
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 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 Submit.
