The OfficeConnect Cable/DSL Secure Gateway has the ability to
dynamically allocate network addresses to the computers on your
network, using DHCP. However, your computers need to be
configured correctly for this to take place. To change the
configuration of your computers to allow this, follow the
instructions in this chapter.
If your computers are configured with static addresses (also
known as fixed addresses) and you do not wish to change this,
then you should use the Discovery program on the Gateway
CD-ROM to detect and configure your Gateway. Refer to
“Using
Discovery” on page 65 for information on using the Discovery
program.
