Assigning static Internet information to your PCs
In some cases, you may want to assign Internet information to
some or all of your PCs directly (often called “statically”), rather than
allowing the VisionNet 202ER to assign it. 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 (subnets are
described in Appendix A).
Before you begin, contact your ISP if you do not already have the
following information:
 The IP address and subnet mask to be assigned to each
PC to which you will be assigning static IP information.
 The IP address of the default gateway for your LAN. In
most cases, this is the address assigned to the LAN port on
the VisionNet 202ER. By default, the LAN port is assigned
this IP address: 10.0.0.2. (You can change this number, or
another number can be assigned by your ISP. See
Chapter 5 for more information.)
 The IP address of your ISP’s Domain Name System (DNS)
server.
On each PC to which you want to assign static information, follow
the instructions on pages 18 through 21 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 VisionNet 202ER’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.

Default Router Settings
In addition to handling the DSL connection to your ISP, the
VisionNet 202ER ADSL/Ethernet router can provide a variety of
services to your network. The device is preconfigured with default
settings for use with a typical home or small office network.
Table 1 lists some of the most important default settings; these and
other features are described fully in the subsequent chapters. If you
are familiar with network configuration, review the settings in Table
1to verify that they meet the needs of your network. Follow the
instructions to change them if necessary. If you are unfamiliar with
these settings, try using the device without modification, or contact
your ISP for assistance.
Before you modifying any settings, review Chapter 4 for general
information about accessing and using the Configuration Manager
program. We strongly recommend that you contact your ISP prior to
changing the default configuration.
