3.2.6 Assigning static IP addresses to your PCs
In some cases, you may want to assign IP addresses to some or all of your PCs directly (often called
“statically”), rather than allowing the Internet Security Router to assign them. This option may be desirable (but
not required) if:
„ You have obtained one or more public IP addresses that you want to always associate with specific
computers (for example, if you are using a computer as a public web server).
„ You maintain different subnets on your LAN.
However, during the first time configuration of your Internet Security Router, you must assign an IP address in
the 192.168.1.0 network for your PC, say 192.168.1.2, in order to establish connection between the Internet
Security Router and your PC as the default LAN IP on Internet Security Router is pre-configured as
192.168.1.1. Enter 255.255.255.0 for the subnet mask and 192.168.1.1 for the default gateway. These settings
may be changed later to reflect your true network environment.
On each PC to which you want to assign static information, follow the instructions on pages 11 through 13
relating only to checking for and/or installing the IP protocol. Once it is installed, continue to follow the
instructions for displaying each of the Internet Protocol (TCP/IP) properties. Instead of enabling dynamic
assignment of the IP addresses for the computer, DNS server, and default gateway, click the radio buttons that
enable you to enter the information manually.
Note
Your PCs must have IP addresses that place them in the same
subnet as the Internet Security Router
’s LAN port. If you manually
assign IP information to all your LAN PCs, you can follow the
instructions in Chapter 5 to change the LAN port IP address
accordingly.
