get a static IP address from your ISP. A static IP address can cost
more money than a dynamic IP address.

DHCP: A
dynamic IP address
is an IP address that an ISP lets
you use temporarily. ISPs use DHCP (Dynamic Host
Configuration Protocol) to assign you a dynamic IP address.
With DHCP, your computer does not always use the same IP
address. Each time you connect to the ISP, a DHCP server
assigns you an IP address. It could be the same IP address you
had before, or it could be a new IP address. When you close an
Internet connection that uses a dynamic IP address, the ISP can
assign that IP address to a different customer.
•
PPPoE: An ISP can also use PPPoE (Point-to-Point Protocol over
Ethernet) to assign you an IP address. Usually, a PPPoE address
is dynamic. You must have a user name and a password to use
PPPoE.
The ISP also assigns a subnet mask (also known as the netmask) to a
computer. A
subnet mask
divides a larger network into smaller net-
works. A subnet mask is a string of bits that “mask” one section of
an IP address to show how man
y IP
addresses can be on the smaller
network.
Read your DSL or cable modem instructions or speak to your ISP to
learn if you have a dynamic IP address or a static IP address.
Finding your TCP/IP properties
TCP/IP (Transmission Control Protocol/Internet Protocol) is the pri-
mary protocol computers use to connect to the Internet. To use
TCP/IP, your computer must have an IP address and information
about the computer network of your ISP. You must have this infor-
mation to install your Firebox X Edge.

If your ISP assigns your computer an IP address that starts with
10, 192.168, or 172.16 to 172.31, then your ISP uses NAT (Network
Address Translation) and your IP address is private. We recommend
that you get a public IP address for your Edge external IP address.
If you use a private IP address, you can have problems with some
features, including VPN.
