WatchGuard Firebox SOHO 6.1
The most common method to distribute IP addresses is 
dynamically using DHCP (Dynamic Host Configuration Protocol). 
When your computer is connected to the network, a DHCP server 
at your ISP automatically assigns it a network IP address. This 
relieves the ISP of the responsibility to manually assign and 
manage individual IP addresses.
Another method of dynamically assigning IP addresses is called 
PPPoE (Point-to-Point Protocol over Ethernet). PPPoE combines 
some of the advantages of Ethernet and PPP by simulating a 
standard dial-up connection. It is popular among many ISPs 
because it allows them to use their existing dial-up infrastructure 
such as billing, authentication, and security for DSL and cable 
modems.  When configured to use PPPoE, the connection can be 
manually connected or disconnected from the System Status page.
Contact your ISP to determine which method they use to assign 
your IP address.
Configure the SOHO 6 External Network for 
dynamic addressing
The SOHO 6 is configured to obtain its external address 
information automatically using DHCP. If your ISP supports this 
method, the SOHO 6 obtains all necessary address information 
when it powers on and attempts to connect to the Internet. No 
further configuration of the SOHO 6 is required.
