4.4.3.2. Existing installations without a DHCP server
In existing installations where TCP/IP has been previously configured and there is no existing
DHCP server, there are two basic sets of options; using each PC’s existing IP address or using
the OmniConnect’s DHCP server to assign (or reassign) each PC’s IP address. In addition,
there may be requirements to allow certain pre-existing global IP addresses to be visible to the
Internet and therefore not assigned by the DHCP server. TCP/IP configuration parameter
settings for these options are described below.
4.4.3.2.1. Use of existing IP addresses
The following procedure must be followed for every PC on the network attached to the
OmniConnect access device.
1. Click the Network icon in the Control Panel Window. Highlight TCP/IP and click
Properties. If TCP/IP does not appear in the list of installed components, refer to the
previous section on installing TCP/IP.
2. Set the Gateway address to be the IP address of the OmniConnect. The default IP address
of the OmniConnect access device is 198.162.1.1. If necessary, this should be changed to
reflect the existing IP addressing scheme. In addition, the default subnet mask of the
OmniConnect must be changed to match the existing IP subnet.
3. Set DNS Configuration to Enable DNS and assign Host, Domain and DNS Server
addresses as provided by the ISP and system administrator.
4. Leave all other screens untouched.
5. Click OK twice and restart Windows®.
4.4.3.2.2. Use of the integrated OmniConnect DHCP server
Follow the procedure outlined in the section titled New Installations for all new PCs and for
existing PCs that do not require external visibility of their IP address. For any PC with an
existing IP address that is not capable of DHCP or requires its IP address to be visible across
the OmniConnect access device on the Internet, follow the procedure outlined in the section
titled Use of Existing IP Addresses. In addition, the OmniConnect access device must be
configured to exclude the IP addresses of these PCs during the configuration process. This is
explained in detail in Chapter 5.
4.4.3.3. Existing installations with a DHCP server
In existing installations where TCP/IP has been previously configured and there is a DHCP
server, the OmniConnect DHCP server must not be used. If the OmniConnect access device is
to be used for Internet access, the existing DHCP server must be configured to provide the
OmniConnect’s IP address as the new gateway address. All other TCP/IP configuration
parameters can remain unchanged.
