Configuring NBX System Networking 103
Table 21 IP Addressing and the NBX System
Local IP Environment NBX System Configuration
No IP networking
currently in use You do not need to change the IP settings in the NBX
system, but you probably need to configure the IP settings
in the computer that you use to communicate with the NBX
NetSet utility.
Set the computer’s IP parameters to these settings:
■
IP address: 192.168.1.191
■
Default gateway: 192.168.1.1
■
Subnet mask: 255.255.255.224
If you connect the LAN to the Internet in the future, your
Internet service provider gives instructions on how to
configure the IP settings of devices on the network. You
must change the IP settings of the NBX system at that time.
Private IP network,
no subnets You probably need to change the NBX system IP address to
conform with the existing IP addressing scheme.
You must change the NBX system default P address
(192.168.1.190) if that address is already in use on the
network or if you are using a different range of addresses.
Private IP network,
with subnets You probably need to change the NBX system IP address to
conform with the existing address space. You must change
the NBX system default IP address (192.168.1.190) if that
address is already in use on the network.
You must change the NBX System subnet mask
(255:255:255:0) if it does not conform to the network
subnet scheme.
You must change the NBX system default gateway from
0.0.0.0 to the IP address of the default gateway for the
subnet where you install the NBX system.
Internet connectivity;
addresses provided by
the Internet Service
Provider. You must change the NBX system default IP address,
default gateway, and possibly the subnet mask. Ask the ISP
to provide a static IP address, subnet mask, and default
gateway.
Internet connectivity;
addresses provided
from address block
controlled by the
client’s organization. You must change the NBX system default IP address,
default gateway, and possibly the subnet mask. Ask the
local network administrator to provide a static IP address,
(the NBX NCP does not support DHCP or BOOTP) a subnet
mask, and a default gateway.
