If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask. If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. You must also enable Network Address Translation (NAT) on the VFG. Once you have decided on the network number, pick an IP address for your VFG that is easy to remember (for instance, 192.168.10.1) but make sure that no other device on your network is using that IP address. The subnet mask specifies the network number portion of an IP address. Your VFG will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the VFG unless you are instructed to do otherwise. Private IP Addresses Every machine on the Internet must have a unique address. If your networks are isolated from the Internet (running only between two branch offices, for example) you can assign any IP addresses to the hosts without problems. However, the 107

Configuring IP Addresses
Where you obtain your network number depends on your particular situation. If the ISP or your network administrator
assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will
assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select
a network number from 192.168.0.0 to 192.168.255.0. The Internet Assigned Number Authority (IANA) reserved this block
of addresses specifically for private use; please do not use any other number unless you are told otherwise. You must also
enable Network Address Translation (NAT) on the VFG.
Once you have decided on the network number, pick an IP address for your VFG that is easy to remember (for instance,
192.168.10.1) but make sure that no other device on your network is using that IP address.
The subnet mask specifies the network number portion of an IP address. Your VFG will compute the subnet mask
automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the VFG
unless you are instructed to do otherwise.
Private IP Addresses
Every machine on the Internet must have a unique address. If your networks are isolated from the Internet (running only
between two branch offices, for example) you can assign any IP addresses to the hosts without problems. However, the
